Hello David,
Correct me if I wrong but in the latest version (1.0.11) the performance monitoring is not supported anymore and when I try to run the process (via a real mobile device) the mobile app got crashed. That is why we've tried to use other Firebase plugin for the MABS 8.0 builds. This is the original node logic flow inside the firebase mobile (v1.0.11) module:

All the client actions were redirected to the False branch, and then I try to modified the node to enable the function, but whenever the process is being executed the app always got crash (tested on Android 12). Hence why it's been set to false
