I’m experiencing an issue where the UCP is endlessly loading, making it unusuable.
This seems to be similar to this issue from 2018.

I’m on PBX version 15.0.16.73 with system version 12.7.8-2008-1.sng7 and UCP module version 15.0.6.18.

Browser console output:

Error with Feature-Policy header: Unrecognized feature: ‘ambient-light-sensor’.

Error with Feature-Policy header: Unrecognized feature: ‘speaker’.

Error with Feature-Policy header: Unrecognized feature: ‘vr’.

Uncaught ReferenceError: UCPMC is not defined at jsphp_939240f3e044e6583b6a49c2767e459d.js?load_version=v15.0.6.18:1

This is a system that has been restored from another install when I migrated from physical hosts to VMs.

Here was mentioned that replacing the UCP’s directory with that of a fresh install could help, but I wouldn’t want to do that before making sure there wasn’t another way.
