I have the ring app on my iPhone and my iPad. Usually it is running in the background. My wife has it on her iPhone. We have automatic updates set up for apps.
If I change the mode from disarmed to away on the iPhone I get a notification on the other devices that the mode has been changed. If the iPad app is open the mode also changes. However, if the app is running in the background, although I do get the notification, the mode doesn’t change when I return to the app: it continues to reflect the previous status. If I completely restart the app, it does reflect the change correctly. In other words, the only way to be certain that the mode is correctly shown is to always close off the app completely when not using it. I find it hard to believe that this would be your recommendation. But I also find it hard to believe that after all this time and all these complaints this problem has still not been solved. Am I missing something?
