Along with a million others, I am having this same issue.
2 years ago, we had this issue (and so did the community). support said "get a new one", so I did. The brand new versa had the same issue. we kept being told "nah, it's your device".
3 days later, both my old and new one got an update and it started working normally again. Which was OK, I passed my blaze on to my wife and have used the versa ever since.
A couple of days ago it started with the syncing issue. it would be less of an issue if the time would keep.
Now, each day, I have to repeat the turn off/forget/delete app and go through the process again to get it to sync. Sometimes you have to do it several times. There's no exact pattern. just repeat the same steps until it works. 10 minutes later it stops working. sometimes it will sync with my computer, sometimes not. sometimes on the phone, sometimes not.
Fitbit, this is not a way to keep loyalty. Just say "hey, there's an issue and we're working on it". Posting the same unhelpful steps that don't work is lazy. I'm even in tech support and I'm frustrated enough to just stop using it.
Otherwise, when it works, it's a great product.
