Update: I received a note from the TR Support Team to try something different - in the apps settings, change the “battery” settings for the three ANT+ apps (ANT Radio Service, ANT USB Service, and ANT+ Plugins Service) to “Unrestricted”. I did this, and magically my ANT+ worked perfectly again! I have already ordered the WYUR and it is supposed to be delivered today, so I’ll have that for a backup, but it’s nice that my current setup will still work.
I hate it when OS updates change these settings and it’s nearly impossible to figure out. So glad the TR team was able to come up with this suggestion!!
