Penalty of the background URLSession in the Main App

[phil1995]

Although Apple states in the documentation that the delay of the background URLSession is set to 0 when the app comes to the foreground:

The delay is reset to 0 whenever the user brings your app to the foreground. It also resets if the delay period elapses without the system resuming or relaunching your app.

The background URLSession in the main app in the foreground is penalized. See also: Apple Developer Forum, ownCloud Issue.

This does not affect the FileProvider.
Therefore it is probably necessary to use a foreground URLSession for the login to a CloudProvider account & the installation process of a Vault to reduce the delay. The authentication at GoogleDrive (via AppAuth) is also done with the default shared URLSession (foreground URLSession).
