### Steps to reproduce

I have a shortcut on my smartphone that points directly to a folder on my Nextcloud server.

When I open this shortcut, I get an error.

If I start the Nextcloud app first and then open the shortcut, it works without any problems.

The Nextcloud app is configured so that Android doesn't close it and allows it to run without restrictions.

### Expected behaviour

The linked folder should open without errors.

### Actual behaviour
