P: Unable to advance to the next photo

Friends, I finally got a response from ADOBE. Here's what they told me: "I really appreciate your time and patience. As checked, this issue has been already reported and a log has been already created for it. Our engineering team is working on it. This should be fixed in upcoming updates of Lightroom Classic."  I hope it's soon!

@DdeGannes  You misunderstood what I was writing. I didn't mean navigation or keyboard shortcuts. I meant using these buttons to correct for example the exposure, instead of doing it with the mouse on the slider! That's what I mean. i.e. I correct a photo with the + or - buttons and can't go to the next photo. If I do it with the mouse, there is no problem. That's it 

Im having the same problem, in develop module, when I increase or decrese exposure with + or - when I click the right arrow, the photo doesnt change, and i need to go back, and the forward again, as a wedding photographer, i have about 4000+ photos of every event, im losing hours editing because of this bug
I have a macbook pro m1, 16" I tryed to uncheck the gpu render, and use only cpu, but the probles is still ther, I tryed to restart, purgue cache, but nothing 

@vitalyn38151610 , In your opening post you stated "Anyway, I did some research and I realized why many people are silent about it, because this problem occurs only when using the +\- buttons on any keyboard, even on macbook !!!!."

I have also done extensive checking and cannot find any information that the + or - keys can be used to navigate through thumbnails in LrC.
I have checked on my iMac running macOS Big Sur and LrC 12.5 and my Windows 11 Laptop with LrC 13.

Do you have any information that indicates that those keyboard shortcuts can be used for this purpose with Lightroom Classic?

There is an extensive keyboard shortcuts list in PDF format that can be obtained from Lightroomqueen.com forum.

@Martinomac  ADOBE does not confirm the status of the error because the so-called "experts" do not see it for some reason, all the experts who wrote here, think only about themselves and that everything works for them, and they absolutely do not care about others, about us, who present them facts, photos with the problem and I am afraid that we can stay with this error and stuck on the old version 12.5. I did not think that ADOBE is such a slippery organization, which is not possible to contact directly!

I have been able to get around this issue - somewhat. Albeit, its not most efficient - it works if you're stuck on v13.0.1.  

I've discovered that if I edit an image quickly and move with my rigth arrow key to advance, sometimes the main image does not appear (does not match the filmstrip image).  So what I did was, make my edits, then wait for the top left preview (in Navigator) to render. Then, if you advance, it will always show the correct image.  It appears that this is a smart preview/render issue.  

For those with fast machines that work with high volume projects like myself (wedding photographer), even waiting 1 full second for the preview to render is too long as I've never had to do that with my M1 Mac Studio.

What's more worrysome is that Adobe doesn't even set this bug as 'Aknowledged'. Come on Adobe!

Just chiming in here again.... I did the update last week when I was halfway through a wedding. So, to finish it, I ended up exporting all the edits I already finished. Then renmaed the raw files in which I culled. THEN, went back to 12.5 and reimported everything. It worked.  I'm now back running 12.5 and I'm not updating anything until I hear the new update is working and fixed. So for anyone like me that's stuck in the middle of a job, the above works fine.

I then went back to 12.5, reimported those finished jpegs, and finished the 

Excactly the same issue here. Filmstrip advances but the main doesn't. The edits you perform are done on the photo in the main view.

I don't seem to get it when i use cmd + arrow to advance the images, nor do i get it when i use the next and previous on my loupedeck.

I tried optimizing the catalog, but that didn't help anything.

@AxelMatt  This is just a mockery, yes, I did everything that was said here, and settings reset too, and rolled back to version 12.5 and again updated lightroom to 13.0.1 the result is no result, as soon as I process a photo on the keyboard, to go to the next with the first time is not possible. Check out the screenshot of the screen, I did it just now. Version 13.0.1 In the ribbon one photo is highlighted, on the screen another. Why this was not in version 12.5 ? It's the same on Windows. I'm not the only one with this problem. Sorry
