I have enjoyed this calendar for 9mths so much so I paid to go Pro, now 3weeks on it no longer syncs events older than two weeks and I need to refer back further. The app blames google for the limitations but I now have another calendar that syncs back 3yrs so nothing to do with google. There used to be an option on BC to syncs all events past and future but this option is no longer available. Really disappointed as was a good app, see how you get on but don't waste your money upgrading like I did 🙁
