After a few hours of trying tons of answers, this is what worked.
Go into the app and change the clock face. I know, this sounds ridiculous. I am telling you I tried everything prior to changing the clock face through the app. I 'forgot' the device in bluetooth, I deleted the app and reloaded, I did it again... I did ALL of the suggestions in the forum and also watched YouTube videos. I turned my phone off and on. My Sense couldn't find the wifi / bluetooth, etc. etc. etc. The big RED X kept staring me in the face......
Changing the watch face worked. If you have tried everything else, it won't hurt to try this fix.
Once I changed the clock face I was then able to connect via bluetooth and then IMMEDIATELY updated the software on my watch. Make sure you update the software!
I hope this helps. Good Luck.
