Bug - Normal Calendar Reset itself

[kilkennygurl]

When I opened up the app this morning, it was slow and glitchy, and when the monthly rewards calendar showed up, it was reset back to the first day. After that, the app got stuck in the vertical orientation of my phone. I've tried closing the app, logging out and logging back in, and even deleting and redownloading it, but the calendar seems like it was still reset

The login rewards reset monthly and today's the first day of may, that's normal
