I would like to confirm that you have checked that the new In-App Notification" toggle is off, per the recent app updates. The app should have a toggle under your device settings, follow these steps to confirm it is off:
Tap “Device Settings”> tap “Alert Settings” > tap “Notification Preferences”> then confirm that “In-App Notification” feature is toggled off.
Having this feature toggled off should ensure a live event will automatically open to full screen when you are actively in the Ring app. If it is toggled on, or if you are not actively in the Ring app, then you will get a notification banner as normal.
If you are experiencing a concern with this feature not behaving as described here, can you please provide an example of the concern. A screen recording example of the behavior you are experiencing with the “In-App Notification” feature toggled off would be ideal for us to share with the app team.
