I don't know if anyone will know or not but will the extended maintenance on iOS mean our attendance rewards will reset? 

No, you will have missed days. The core server serves both Android and IOS, and doesn't care about what client is making use of its services. Which means, you will be like an Android user that didn't pick up their phone and log in for 2 days.

Well damn, that sucks, but thank you for replying!
