Question: https://www.elevenforum.com/t/how-to-keep-all-notifications-in-windows-11.44371/
"in Windows 11 I have enabled all notification permissions, allowed apps to access notifications, and turned on the sliders for system apps, yet some notifications disappear immediately after appearing and are not stored anywhere. I have also tried tools like Notification Logger, but the situation hasn't improved. Is there a reliable way to ensure that all notifications are retained?"
AlomWare Toolbox solution: The app has a setting to auto-snapshot every notification as they appear, so you can later view what they looked like at the time. The setting is here:

The auto-snapshots of them are found in the Screenshots tab for later perusal (see below). You can filter the screenshots to show only notifications by specifying "Notification - " as the filter text. When filtered, you can bulk-delete them by selecting them all with Ctrl+A and pressing the Delete key.
