I purchased a TomTom runner 3 yesterday and updated it with the new software 1.7.53, the watch will not pair with an iphone 7 that has ios 11. I have deleted the app from the phone and installed it again, reset the watch to the factory settings and started over, restarted the phone, nothing works. pretty disappointed and frustrated with this, any help would be much appreciated. How do I fix this?
