The issue had been synching it once it was paired.
No issues with my Google Pixel 2. But, that has the latest & greatest Android software. Nonetheless, that serves as a baseline. Now that I can get it to SYNCH on my Pixel 2 we can move on.
Just wanted to share this with YOU.
I haven’t spent much time with the Charge 3 because I have had my hands full with the Polar Vantage V.
Did, however, pair it to an Android phone. Pairing worked fine. Then discovered that I can’t SYNC it!
So, removed it from the phone and paired it AGAIN. Still can’t synch.
A little bird has told me that this might be a KNOWN issue — at Fitbit!
I am a bit put out. I will, of course, keep you posted.
