From Garmin Connect App -> Connect to MFP, Authorize, "Account Linking Failed". Then I go back and it's linked with the only option to "disconnect". However, it's not fully linked. If I log a food, even a single apple puts me in negative calories since the goal calories are 0. It's not syncing goal calories or exercises I log in MFP.
I have tried uninstalling both apps completely, reinstalling them, and even tried using my computer to link. On the computer when I try to link to MFP it just says "Just a minute. We're syncing your accounts" and sits there forever.
