Hi @Laz-Kitao @uapilot,

Hope you are doing well. Sorry for your experience with Acrobat Reader Mobile.

I have reported the issue to the team for further investigation. 

Would you mind sharing a sample file with us to reproduce the issue and get it investigated further?

This would help us understand and get to a fix quickly.

Also, a screenshot of the error you see would be great.

Look forward to hearing from you.

I thank you for your response.

I don't mind sharing the files that cannot be opened.

But the error-files are over 500MB, and I think the maximum size to attached is 47MB.

How can I share the large-sized files?

I use Google Drive, and I can share them on Google Drive.
But if another way you prefer exists, please teach me. I do the way.

In this message, I attach a screenrecord movie about failing opening pdf files on iPad.

Plus:
I found that I cannot open large-sized file on android device too.

 (981MB, Gray+Color, 346 page, 176.7x234.2mm)
I write the device info below.

=== === ===
[ DEVICE INFO ]
Device 1
- OS = iPadOS 16.4.1
- Adobe App = 23.03.01 (20230330.152506)

Device 2
- OS = Android 13
- Adobe App = Adobe Acrobat 23.3.0.26648

(I'm sorry for my poor English...)

@Laz-Kitao,

Thank you for sharing the details.

Would you mind sharing the file with me through Google Drive? You can generate a share link and share it with me over private messages (click on my profile name-> click the blue button saying "Send a message" on the next page)

@S. S

Thank you for guiding me about sharing large files.

I sent a link of Google Drive over private messages.
There is 1 PDF file.

If you don't receive the message, or can't access Google Drive via the link ; please let me know about that.
I might mistake something, and I will retry.

[uapilot]

This is the problem because only the files over 500MB will not open and are considered "corrupted" when that are not and open just fine on my Adobe Acrobat DC on my desktop and laptop!!!!!! That's where you Adobe fools screwed is over with this last LOUSY IPDATE!!'

Hi @Laz-Kitao @Anila29319934quuh @uapilot,

Thank you for sharing the files with me, and sorry for all the trouble with the file opening.

While I understand how frustrating this might be, our team is working and keeping the issue a high priority to be fixed in the upcoming update.

I request your kind understanding and patience while the team works on it.
