Thanks for reporting oiselarius!
Can you pls add if opening an odf file from the storage on the phone does work?

[oiselarius]

If I transfer the file from cloud storage to the phone it seems to work. I don’t know why the same files stored on a cloud server won’t open.

edit: Collabora for iOS won’t open files on cloud servers other than iCloud. I use Google Drive but I also have OneDrive and DropBox and it won’t open them but if I pay for storage on iCloud it will open them.

Looking into this now. As far as I recall, other storage providers used to work just fine. There certainly is no intentional code in our app that would restrict it to open files from iCloud, or prevent ODF documents from being opened from Google Drive, so please avoid the insinuations ("I thought Collabora was open document friendly") thanks.

I just tried opening a .ods document from OneDrive and it worked just fine. (This is using the latest TestFlight build.)

But yeah, for some reason all ODF documents in Google Drive are greyed out in the app. This is probably Google Drive's fault.

The fix for this seems to be to move the ODF entries for the ODF file types from the UTExportedTypeDeclarations section to the UTImportedTypeDeclarations section in the Info.plist. (Sadly the documentation for exact semantics of the Info.plist file leaves much to be desired.)
