1. Initial situation
Basically, apps from the Google Play Store update automatically, but that doesn't seem to be the case with me. What can I do?
2nd solution
- Open the work container's Google Play Store (if you own the device, there is only one Google Play Store)
 - Click the gray circle in the upper right corner
 - Choose Settings
 - Choose General
 - Select Update apps automatically
 - Select "Via any network" or "Only via WLAN" depending on your own requirements
 - Confirm with Done
