Getting duplicate notification on every event in every camera. Just stayed in the last 2 weeks.
Do you have both sound and motion alerts enabled possibly?
I often get the notification sound twice, but the actual notification is only there once. If you’re getting dual notifications but there is only one event in the app, I’d probably try uninstalling and reinstalling the app (assuming you’re on the 3.x app). The update to 3.1.0 actually stopped all notifications for me until I reinstalled it, and that was about 2 weeks ago.
