Seeing at the images in Red with ? Samsung Devices.
Note that we do use Samsung Tablets. But "only" Android 8.
I´ll check the app for sure ;-) Thank you for pointing me into this.
Basically, when a user reports that one of my apps are being killed by the OS, I have them visit that website and they are usually able to try the applicable methods mentioned on the site for their device to fix the issue.
I have not used the site's app myself yet, so I don't know much about it.
