Blokade 6, Moto G82-5G, Android 13. Installed from Google Play Store.
Notification icon of active B6 not shown on screen.
Settings of notifications are all enabled. Reinstalled and reinstalled B6, but did not help. Used B5 before, although I had a license of B6. Notification icon of active B5 was visible. B6 not 100% stable, sometimes B6 is disabled temporarily. Enabled automatically, sometimes have to do it manually. Notification icon is very helpful. Reused B6 again because local VPN required for another program.
