Beta, from a year ago? Are you are building the new version of the app from GitHub. Apple self-signed certs without Apple Developer accounts only last 7 days and then the app needs to be signed again.
Your log shows the current 1.13.0 app from the the iOS App Store and current Passbolt version. I have it running on my iPhone without issue.
The Passbolt health check is showing a few “Helps” have you tried fixing those issues.
Have you tried deleting the “beta” app and then reinstalling version 1.13.0 from the App Store
If you turn off your Wi-Fi and use your cell data does the app work?
Can you explain the beta and final part?
