It works at first but after awhile the sync stops and can't resolve the name. And the iCal events have changed but it doesn't reflect on calender in my Phone. 😭, Update - 11/2/21. Now my autosync is disabled with no reason. So I have to make manually update it. - Update 11/10/21 - I followed the instructions to make sure the app doesn't go to sleep but events that are on my calender will have been updated with new date and time won't reflect thru the app. Lost a star for it.

please update to version 2.0. Maybe it works better for you. please make sure you have enough disk space, otherwise the sync can be blocked by the system
