since it’s not possible in iOS to set a third-party App as default viewer for PDF files its kinda complicated to open them in a specific app.
Open the file in Seafile with default viewer > Go to “share” or “open in” > Select App
This step is required every time when opening files with third-party apps.
It would be nice if its possible to set the default app for specific file types in the iOS Client.
Is this possible to realise? Does some1 else see the need for such a feature?
