I checked logs:
Sever start with log: info: [plugins/web-push] VAPID keys OK.
Nodebb: 4.4.3 Plugin: nodebb-plugin-web-push 0.7.4
it works on: Desktop + Android But I don't have any permission request popup to enable notifications for Nodebb on Safari Mobile and iOS I tried also with homescreen app in iOS
Can anyone help me? julian maybe it is worth to check this behavior in Browserstack?
