Mode-notificions NOT working

Despite an early discussion in this thread https://community.ring.com/conversations/ring-app/turn-off-notifications-in-modes/6580392851f6e6fe78e276b6 we are experiencing the opposite. In our account we have a main-user (Andorid 14) and a shared-user (Andoid 12), both using the most recent Android Ring-app. Notifications for motion-detection as well as doorbell-Rings are working properly: a popup with camera-picture, together with a double ring-tone. Now the problem: until last week we received a pop-up notification with ring-tones when one of us was changing modes. Very useful to know if one of us arrived- or left home, but unfortunately, this notification is not working anymore, while we are not able to turn this notification off or on in the app or the central functionality on the web. Because we experience the problem from the same time on both devices, the problem can’t be caused by the apps or Android settings. If it should be caused by Android, than it will be a setting in general, not only for a single notification of an app, while the other notifications of the app and all the other apps are working properly. It must be caused definitely by something in the ‘central functionality’, but even the helpdesk was not able to solve this in several attempts. Yes, helpdesk gives the predictable advise to reinstall the app, but that is repeatedly far away from a solution. Anyone with an idea to solve this? Headquarters, please help!
