I have not installed the Zwift app on my phone but continue to get zwift notifications and videos on my android phone which also give an audible notification, I do not have an app to change settings to stop them, and aside from really irritating it is a problem from me at work! How can I stop them?
When you next get a notification press and hold the notification and it’ll bring up a slider. Set this to off and then save. Notifications no more.
