Sorry that you're getting an error message while opening a cloud document on Photoshop on the iPad version 1.6.
Have you tried signing out and then signing back in again? Another thing you might try is to sign out and then back in on your desktop computer(if using) and then try your iPad again.

Let us know how it goes.
I did, but nothing worked.
I still could open the file on web, but not within the app itself.
Would you mind reinstalling the app and let us know if that helps?
I did re-install the app and still got the same error.
Thanks for the update. Would it be possible for you to share the file link with us so that we may try reproducing the issue?
It appears that we are having problem opening the file because it is in bitmap color mode. If you convert it to grayscale or rgb it will successfully open. You will get a message on opening the grayscale that it has unsupported features because there are some features that we do not fully support with grayscale images yet.
We will look into why bitmap is failing to open. Thanks for reporting this.
It's strange as this file was being opened and edited successully before version 1.6. Now, I just wanted to edit again and it gave error.
Yes, it is a recent breakage. We will look into what changed to cause this.
