I had made a separate thread asking if people were having an issue connecting their HRM-Tri (And most likely their Run) after the 2.72 beta, because my watch not only stopped; but spit it out of my list of connected devices and refused to reconnect to it. Sent that info off to the beta team which told me that they were working on the live 2.90 and...then didn't give me any more info than that. I had hoped that some quick fix might have come thru with the live 2.90
I hoped wrong.
Not only did my HRM-Tri not work....but my stable Polar H10 that worked just fine in the beta, started to go nuts on the live. That's right, both BTS and Ant + external sensors would not work with the watch. Not only that....but not I was getting internal GC messages telling me that my watch was disconnecting from CG and that I needed to troubleshoot the problem. You've most likely had the same message from time to time. So, I did all the troubleshooting options, up to re-pairing the watch from the app. For a few days everything seemed fine, but then i'd get the message and have to troubleshoot.
It was around this time that the H10 just would not connect that I gave up and just removed the watch from app from GC. After doing that, I got the idea to just remove all the sensors from the watch and try re-pairing them...and you know what....everything paired, the H10, the HRM-Tri even my Stryd (which stopped connecting) all were recognized after the watch just stopped.
So i'm just taking an educated stab in the dark here, but if you come up against an issue in the future where your watch stops recognizes your external sensors (BTS,ANT+), Disconnect the watch from the app altogether first and then try re-pairing the sensors. Whatever the issue I had came from the unstable connection from the watch and app regardless to whether the sensor is BTS or ANT +. The watch just goes off the deep-end if it isn't properly paired with the app and starts messing with the singles to external sensors.
I hope this helps anyone coming up against similar issues.
