Hi Wade,
Sorry I forgot to reply here as I had already replied to your direct support email.
Just so that the answer is available to everyone, here is the reply I sent Wade via email:
Hi Wade,
Yes, this is the default calendar as set on your device. To change this:
- Go into the Settings app (not Settings in myCal)
- Tap Calendar
- Tap Default Calendar, and make a new selection
Let me know how you get on!
Regards
John
