I was on day 600+ and did not miss a day but today i"m on day 1. What happened?

Hello @al721 welcome to the Community!

I am sorry to hear that your daily bonus is reset to day 1. It cannot be restored 🙁.

There are a number of reasons this reset might happen: device updates, the time you logged in, and one-time glitches may cause this. Though your Daily Calendar progress cannot be restored, rest assured that your actual rewards are unaffected. You can keep collecting and enjoying your rewards every day!
