Once a great app, now unworkable – Informant 5 Calendar Review

I was an early adopter of this app. It was great at first, but has become hardly useable. Sync issues are the main problem. It amazes me that this company cannot correct these issues. My calendar now has 5 duplicated events for each day going back nine years. I am done with this buggy app. I switched to Google Calendar, and I am pleased with it. My communications with the customer support group has not helped.
