Since the update to 19.04 the advanced permission rule dialog is broken. When creating a new rule the user list is generated incompletely (about 10% of all users). The search field does not work, it does not find any users (no matter if they are in the partially generated list or not).
Is there a kind of cache for the users in the app, which I can rebuild?
Furthermore this problem still exists:
I am grateful for every hint.
