Apps Crashing Question

Hi All,

I got the AIPaper Mini last week and I’ve been very much enjoying it. There is one issue I’ve been having, though: about 50% of the time I use any app (60% for Daily and KOReader), it suddenly crashes and I get a “This app is not responding” pop up. After that I reopen and everything is fine. It happens to Daily any time I ask it to sync my calendar.

Is this experience typical? I am running the most current OS and frequently close unused apps in task manager.
