Yes, I'd need to see this in the app's debug log, there is no other way for me to know what happened and how.
If you're interested:
- Please enable debug logging as described below in my signature, with "raw session data" enabled, on the "bad" phone
- Update the "bad" event using web mail / cal or Outlook or something else, changing its category (color) would be just fine
- Sync the calendar in AquaMail, wait for it to complete (the category / color gets updated)
- Send the log to support [ at ] aqua-mail [dot com] or kmansoft [ at ] gmail [ dot com]
- I will also need to know what the "correct" (expected) time was, and the phone's time zone (name and actual offset from GMT).
