I have a OnePlus 3T Oxygen 4.1.7. I can no longer download/update apps on the Play Store without WiFi, I used to be able to until I accidentally checked to always download over WiFi only.
Here are the things I tried to fix it.
- I've already changed: Play Store > Settings > Auto-update apps to Auto-update apps at any time. Data charges may apply.
- I've also changed Settings > Google > Data Management > Update Drive-enabled app files - Over wifi or cellular.
- I've uninstalled the Play Store and then reinstalled it as well.
- I've restarted multiple times after each of the above steps.
So far nothing works.
