API Key valid/invalid

I’m having the same API issues as others. It keeps going from valid to invalid. Checking the box doesn’t resolve the issue.

I’ve waited a few hours. I’ve created new keys. No change.

Consequently the map also doesn’t now show, the error message is :
Google Maps API error: DeletedApiProjectMapError https://developers.google.com/maps/documentation/javascript/error-messages#deleted-api-project-map-error

What’s going on here? Can you suggest a fix?

Thanks
