Fitbit, a Google company despite barely working with Google the last time I checked, is having trouble with their dashboard and sync today. You can try to log in but get stuck in a sign in loop.
This has been since about 4am CST Feb 6th, 2023. Still in a loop as of 10am CST
I would hope they address that Adobe Flash issue while it’s down, but suspect that’s not going to happen.
As of 2:50pm CST it’s back up, and Adobe Flash is still used on the food logging page.[9to5Google]
