I also have a similar issue with my mobile data connection. When I leave my WiFi area, my phone does not automatically connect to my mobile data connection, which I always leave it on. Then I will not be able to use any app that require data connection. I usually have to manually turn on the flight mode and turn it off, and only after that the mobile data will connect.

@usercpqAXptoFk if the Smart Network Switch isn't working, the only other option I know of is to
go to Settings-Developer Options- enable Keep Mobile data turned out
