Mqtt enabled fully kiosk integration looses connection when device restarts

i have a fully kiosk app running on a device that is not able to have a fixed IP so i have enabled mqtt topics for the device in the hope that the integration would connect to this and update its IP address when it changes - as the device ID does not change. And if i manually remove and add with a new IP address it correctly connects back as if it was the same device for automations.

Is this an intended feature that isn’t working or where can i make a feature request for this integration to make it a feature?

Seems this may be related to the fact that i am runny fully-single-app over fully-single-browser where $appid is different. manually using fully in the mqtt event settings does get it to show via auto-add. will see what happens next time the ip address changes
