Help: PS5-mqtt Addon Not Displaying ActiveApp_Image and ActiveApp_Title

THE ISSUE / PROBLEM / OBSERVATIONS:
Activeapp_title and activeapp_Image entities are no longer detected / available via MQTT broker. On my initial setup a few months ago, they were working. I was never able to get nvm working to create refresh tokens. So, my plan was to just manually refresh the npsso token every couple months by logging in and copying it over to the configuration section. This is the first time I’ve tried manually refreshing the npsso.

WHAT I’VE TRIED
Submitted help request on the relevant Github discussion tab: Activeapp_title and Activeapp_Image Not Working · FunkeyFlo/ps5-mqtt · Discussion #538 · GitHub

Reinstalled / reconfigured ps5-mqtt addon
