I also cannot unlock this achievement. I've changed in-game and device settings off an on for both my PC and my Android device, and cannot get the achievement.
Please let me know if you can fix my issue with the Notification quest. I've turned it off and on multiple times and logged out/on after each one and still do not get credit for the quest
I have the same issue on a pc and it say I need to enable it in my device settings and a relog doesn't stick either as suggested. My id is um67677195 | 65956127
