Mobile Data setting switch, won’t stay in the ‘ON’ position for some of my apps

When I go into the mobile data settings, swipe right so the mobile data turns on for the app, exit the settings, go back to the settings, the mobile data for that app has turned off by itself. I tried to uninstall apps, reboot the ipad, turning airplane mode on and off, and turning mobile data off and on, but nothing seems to work.

Mobile data is working - just not with certain apps. The toggle switch just won’t stay in the kn position. Please help me fix this problem.

p.s. This only happens with some apps - ones that I have turned mobile data on/off before - e.g. Netflix, Google Maps, etc.
