My issue started with the S7. I couldn't download apps while on mobile data. I was and still am able to download apps while on WiFi. Now that I've upgraded to the S8, I still have the same issue. Here is what I've done on the S8 which I also did on the S7 and did not fix the issue. Clear Playstore Cache Uninstall updates and reverted back to factory playstore unlinked my google account rebooted phone ensured data saver was disabled made sure that data usage for Play Store was allowed in the background and just for F**KS sake, enabled "Allow app while data saver ON" Auto-Update Settings for Play Store is set to "Auto Update apps at any time" WIPED phone to factory I think I've hit all possible bases that could cause an app not to download via data. PLEASE help me, I've upgraded phones already, and FKN phone is doing the same thing. I'm using T-Mobile, and hopefully these dudes are not throttling my data... ANY HELP IS GREATLY APPRECIATED!!!!!!!!
