Fitbit version 2.76.1 not Syncing

I have read a lot of the other posts about steps not syncing via fitbit and have tried all of the solutions I have found, including unauthorizing the app via fitbit and then reauthorizing. It has been to no avail. This is pretty upsetting, one of the reasons why I bought a fitbit was because I though this app was a lot of fun and carrying my phone around everywhere was a hassle. It is very dissapointing that syncing with the fitbit is so buggy.
