P: File extension (ex. jpg) not changing during format change after upgrade to macOS 10.15 Catalina

hahaha

> I have been helping Apple Engineers for two weeks with this problem of Photos App not being able to open photos on iPhone or iPad.

No wonder they've not found time to call me for a session. They're too busy with you. (sigh) iPad OS isn't able to preview files in folders that are on my iPad and have never been a problem before. Airdrop is barely even working at all. One file up or down at a time is okay into photos is okay, but not folders, even small ones, into Files or shared from Files.

 I updated to iPad OS for the sake of using a portable drive with it, and it appears by gaining that, I sacrificed the ability to even see the files in folders  that have more than 100 files in them.

All the problems with the latest updates aren't just Adobe's. I'm sorry you're in trouble with it. I'm relieved that I'm not alone  so the engineers can't simply dismiss me—even if they don't call back to make an appointment as promised. They're obviously very, very busy!

Dear eartho, Champion -- neither my life nor my job depend upon installing Catalina, and for me, thus far, the only application that has been seriously affected is an art program wrapped in a Wineskin...it is Wineskin that's causing the problem.  This info was separated from my original post.  As far as the file extensions not being saved to the proper file format, I'm sure that Adobe will correct that as soon as they can.  I will try to install Mojave on an external boot drive and operate the Wineskin software from Mojave on that drive until Wineskin and the Window's program is updated.  I automatically update my software so that I am current and have never had any serious problems.  When you think about it, these developers create some fantastic programs for us, and they provide many opportunities for creativity and the gathering of information.  My hat is off to all of them, because I surely couldn't do what they do!  I will wait for them to correct the problems and work around it in the best way that I can!

Just saying. . .

Whilst I acknowledge that this isn't the same problem that Mac users have with Catalina and Photoshop, I'm beginning to question the whole updated iOS 13 in relation to file compatibility
within Apple system.

I'm having huge problems with www.icloud.com not being able to read .jpg or .jpeg files from photos edited in Photoshop. It doesn't matter which way I save the photos, whether using Save As, etc. or where I source the original photos from. 

Any iphotos which I've downloaded to my Windows PC from www.icloud.com and which I've edited in Photoshop and then re uploaded to www.icloud.com will not open on my iPhone or iPad. 

I know it's not Photoshop, because I can't use any .jpg / .jpeg photo files from any of my Canon or Sony cameras, which I've uploaded to www.icloud.com  My iPhone and iPad Photo App will display the error message: Cannot open the Photo.

I have been helping Apple Engineers for two weeks with this problem of Photos App not being able to open photos on iPhone or iPad. We've had screen shares, file shares, with me listing step by step for them to reproduce the problem and they can't find anything. Today, as a last resort, we shared a logging session where I uploaded a saved edited Photoshop .jpg file to www.icloud.com and my Photos on iPhone 'Could not load Photo'.

For those Mac/Catalina users I have found this Apple support site, which may be of help to you if you have problems with file extensions: Formats compatible with macOS Catalina - These video, audio, still-image, and container formats are compatible with iMovie on Mac computers with macOS Catalina:

I've read the Catalina terms and never EVER is this problem addressd.

Folks, you never, EVER do a day one major OS update if your job depends on your machine running smoothly. For months, all over the internets, it's been strongly advised to not install Catalina if you don't have to.

I have to agree with Barbara—as a customer it shouldn't be our job to play guinea pig for Adobe. It should be Adobe's responsibility as developers to be aware of up and coming updates to OS's and review BETA copies of that OS for any possible incompatibilities before they become issues. I understand that in an imperfect world some things are apt to slip through undetected (which happens way too often) however to make the statement "This is why it is so important to first read the info on compatibility issues and then decide if you upgrade your OS or wait till these kind of problems are solved"—this is just a cop-out. If you know of certain issues, we should be notified through our Adobe CC subscription in a popup message.

This is it. You have a layer file and want to save it as .jpg but you have to type yourself the formate change to be known. Otherwise .pdf file is saved as you opened it .pdf even though you save it as .jpg

Hi, I think we're talking about two different things 🙂 I had originally started up a new chat discussion here, but my issue got merged into this topic, so I think we're both trouble shooting different issues. 

My solution above worked for my issue! Hope you're able to find a solution for yours! 😄

Weird. I'm not able to reproduce that with file that have Maximize Compatibility turned on. If you encounter another file that does this, let me know. I'd like to get a copy of it.
