moved to my fitness pal from fitbit when i got a new watch a few weeks ago

Ronogg

HI, I moved over here a few weeks ago after my fitbit kept giving my fits.. they sent me a new one and it did the same thing. so I bought a samsung s3 frontier watch. I love the watch but have some questions for others who use it and also have a fitbit aria scale. 1. do you use map my run and does it automatically sync with myfitnesspal? 2. I had to transfer all my fitbit weigh ins and it seems they all are syncing now (would it be easier to buy a new ua scale?) 3. do you use any of the other ua apps? 4. map my run keeps stopping the distance traveled but the timer keeps going (this has happened almost every time I use it. usually when i switch over to spotify to change a song or answer a phone call. ) I have been having issues getting them all to work on my watch and have deleted all but map my run and myfitnesspal. Thanks in advance for any help you are able to give me.
