Can't disable opening pdf files on the mobile Nextcloud app

[ottsimon]

I use an older version of the Enterprise Edition Document Server, because I don't get updates for newer versions. This version doesn't seem to work with PDF files in Nextcloud. When you try to open one, you get the following error:

The "documentType" parameter for the config object is invalid. Please correct it.

But I don't need OnlyOffice to open PDF files, because Nextcloud has its own PDF-Viewer. Therefore, I never enabled the filetype in the OnlyOffice Nextcloud settings.

The web interfaces of Nextcloud respects this setting and opens the files in Nextclouds own PDF-Viewer, but the mobile app on Android still tries to open the file with OnlyOffice and fails. In the past the mobile app downloaded the file and opened it with a local PDF viewer on my phone.

Is there a way to tell the mobile app to not open PDF files with OnlyOffice?

Versions:
Nextcloud 29.0.4
Nextcloud Android App 3.29.1
OnlyOffice Nextcloud App 9.3.0
OnlyOffice Document Server 7.5.1

Activated filetypes:

I confirm this, and it seems to be problem with onlyoffice nextcloud app, not onlyoffice server.
I does not matter if pdf filetype is selected or not, behaviour is same.
Meanwhile, i have another software that opens pdf files using same onlyoffice server without problems.

Workaround: downgrade onlyoffice nextcloud app to previous version (9.2.2)
