Opening PDF + Switching Apps = "Document cannot be saved" Screen

[Tex2002ans]

Describe the Bug

On Android, every time you:

• Open a PDF in Collabora Office.
• Swap apps
• then return to Collabora...

you get an annoying "Document cannot be saved" screen. You have to press "OK" to dismiss every time.

Steps To Reproduce

1. Open a PDF.
2. Swipe (or use OS button) to switch to another app.
3. Switch back to Collabora Office.

Expected Behavior

PDF or last page you were on to just appear in viewing mode.

Actual Behavior

"Document cannot be saved." + OK button screen appears.

You have to:

• Press OK

to return to viewing your PDF every time.

Screenshots

This was first reported by Adibuyono in the Collabora forum:

It's their screenshot, but I was able to reproduce exactly the same popup on my end too.

Version Info

I tested this on Android 11:

COOLWSD version
21.11.6.1
git hash: 6706dd4

LOKit version:
built on a great technology base
Collabora Office 21.06.32.1
git hash: e211b5b

Additional Context

(Maybe the same on iOS too? So it may be a broader mobile OS popup/window?)
