Google broke syncing for Fitbit scales (support.google.com)

I've owned a Fitbit Aria Air for nearly eight years. It stopped syncing a few days ago. Google's response is essentially, "we broke it."

I have an ancient Withings scale and a Fitbit, it used to be that Withings sends data straight to Fitbit but these days seems gone, so now I have Withings app writing to Apple Health and then Google Health reads from it. Great time to be alive
