I am pulling my hair out. I have a long story. However, the crooks of it are simply this - the watch will not connect to my iPhone. I've updated, I've downloaded, I've patched-up, patched-on, cooked the dinner, read the manual, listened to the dealer and plugged-in, even had my watch exchanged because I complained the unit was faulty and still not a sausage (even with a new watch out of the box today). I've followed the recommendations here in this forum. I'm at a loss. Anyone actually managed to work out how to get this watch paired up with an iPhone? I've got iOS 13.5. My D2 Charlie pairs in seconds. This F6X Pro ...............well.............!
