Pocket Informant does not work with iOS 14.5. – Informant 5 Calendar Review

My calendar is now bricked since updating to 14.5. Will not even open. No data is available. My iPhone message when trying to open Informant is that the developer of the app needs to update it to work with this version (14.5) of iOS.
