I've noticed you are new around @MeNEwuser, so let me give you a warm welcome to our Community! 
I haven't heard any issue related to Fitbit Blaze at this moment. Can you please confirm which model of phone you're using? Also make sure that both Fitbit App and phone are up to date!
Please keep me posted!

Hi @MeNEwuser, thanks for getting back! 
Thanks for confirming this information, I think that I found out what is happening, this specific model or the LG family is not in the list of compatible devices with Fitbit. 
Same thing happened to me, I have a phone that is very recent so is not in the list either. I've been having syncing issues for a while so what I did is try to "Force quit" the Fitbit App. And I noticed that my tracker syncs every time I do that. It syncs for call and text notifications too. But you'll have to try, for better practices it's best to sync with a compatible device or computer/laptop.
Give it a shot and let me know if that works!
