Skyracer

I have 3 Android devices, 2 phones and a tablet and all 3 have the same issue. KIS works for a few days then closes itself with no warning or alert.Manually restarting works fine for another day or 2 then the same happens. Anyone else seeing the same or have a fix? It's strange that is the same on 3 devices all different manufacturers and different skins and all running the latest version of KIS and OS's up to date (2 Android 8 and 1 Android 9).
