Remember: as part of this change, garmin has adopted more stringent policies on passwords. So first check if you need to update yours by logging in through a browser (not the Garmin Connect app - your garmin web account and your account on the garmin app, if you have it, do not necessarily share the same password). If an update is required, go trough with it and then update the password in my app as well. Note: if you auto-login into connect because of saved preferences, I suggest that you first log out of connect and then log in manually, otherwise you won't be asked for a new password.
As usual, this is the time when I invite you guys to follow the sportablet account on twitter or facebook (links here on the right). There is no marketing going on there. I use those channels only to inform you of important stuff (updates, issues, etc.)
