NextDNS iOS app 3.0.2 - Return of passcode - New Bug

I previously had NextDNS 2.0.1 deployed via an MDM profile, with the app installed through VPP and configured to auto-update when new releases become available.

On version 2.0.1, I enabled the passcode feature and set it to a 6-digit code.

After the app updated from 2.0.1. 3.0.0 and 3.0.1 to version 3.0.2, launching it prompted me for a 4-digit passcode instead. It appears that the app did not retain the existing passcode configuration during the upgrade. 

Can confirm this is happening on multiple Apple devices.

The only way to resolve the issue was to uninstall and reinstall the app. The I needed to re-enter the ID, re-enable the passcode, and then update the device name. This process is quite cumbersome.

I suspect this may be related to the removal of the passcode feature in versions 3.0.0 and 3.0.1. When the feature was reintroduced in 3.0.2, it may not have preserved previously configured passcodes.

It’s also possible that users who installed version 3.0.2 directly (without upgrading from 2.0.1 through 3.0.0/3.0.1) were not affected by this issue.
