Push Notification cannot be enabled

Description

I have installed Rocket.Chat Server Self hosted and di the mistake to choose Push notification via own gateway. I corrected this mistake, registered and agreed to everything, of course read all available information in this forum about this forumd and followed all recommendations. but by no avail I can manage to make the Push service work (yes I tried restarting also) - it greets me with mising user tokens (so it still thinks I am in the self service mode). How can I convince my otherwise nicely running system to get this change ?

… yes I tried the Stetup Wizard again and again :wink:
