Hi @activate.4017 There is a bug in our latest iOS app which causes the crash on iPhone devices with iOS 14.x. We are working on a resolve and should be able to release the fix by sometime tomorrow. Thanks ---

Hi all, The problem was with the latest Apple Development toolset causing all iOS apps which are using a certain database, and are uploaded to the store within the past week to crash on iOS 14 (details are [here](https://developer.apple.com/forums/thread/696197), and Apple’s fix is reported [here](https://developer.apple.com/documentation/xcode-release-notes/xcode-13_2-release-notes)). We implemented the workaround for this and released it to the App Store yesterday. Participants who have this problem should update to the latest version of our iPhone app. Hope this helps ---
