We currently have one use experiencing this issue.
Initially the user had an iPhone 6 running iOS 11. Due to an unknown issue, the device would not update to the latest OS.
When opening the app it would hang indefinitely, in excess of 20 minutes. After trying multiple possible solutions, the problem was attributed to the outdated OS and the user was upgraded to a new device.
Now the user has an iPhone XR which was running iOS 14. Initially AppSheet loaded as expected, no problem. Now the user’s device has updated to the latest iOS 14.2 and we’re back to square one.
AppSheet hangs indefinitely, in excess of 20 minutes.
We have uninstalled & reinstalled the app while power cycling the device in between.
I emailed support when the issue first became apparent and have received one response that the issue was being investigated and have not heard back since then.
