Calendar app glitch in iPadPro
Did I create too many calendars in Calendar app on my iPad Pro (10.5-inch)? Currently I have 9 of them. So whenever I hide some of them to work on others, all of a sudden some calendars would appear, or disappear by themselves whenever I start working of them.
Besides, the sync between my iPad Pro and iMac is not consistent for Calendar, as well for Notes. Though the iMac is relatively old (8 years maybe), and might not be smart enough to catch up with newer iPad.
Thanks for your ideas.
iPad Pro, iOS 12
