Edit: I am not sure what happened because I didn't try anything differently but I was able to get the two to connect!
I am trying to connect my Garmin Connect account (I have the Instinct watch if that matters) to MyFitnessPal account. When I click to connect I get the message "Your MyFitnessPal and Garmin Connect accounts are now connected. Just a minute. We're synching your accounts." However, they never sync and when I check to see if the account are linked (from either the MyFitnessPal or Garmin Connect) they do not show a connected app. I have tried logging out and back into my accounts and tried to do this on a computer but have had no luck. Any thoughts on how to connect them?
