Nest max camera

Hi I have integration for Nest working in HA. 2 thermostats and Nest doorbell.
I had a nest camera max working but for some reason the entity hasn’t been working the last few months.
If I go to Integrations Nest it shows the 4 devices.
If I go the the entities camera.living_room
it has a red exlamation and says: This entity is no longer being provided by the nest integration. If the entity is no longer in use, delete it in settings.

where can I look?
