Lag to wahoo kickr

Hey. Everything used to work beautifully until about a week ago. Typically i run TR beta on macos, spindown in wahoo app, and have the “read power from an ant+ power meter” turned on in settings as well as power smoothing 10s in TR settings. I then launch mywhoosh and turn off “controllable” to have entertainment / motivation beyond red graphs or youtube. Works a charm, and has for months. Erg mode

Last week thursday it started lagging where the resistance doesnt change after the emd of the interval for 15 seconds, and no i terval beeps are audible. The power reading then lags a further minute. Example: interval goes from 306 to 169w, the resistance stays high for 10-15 seconds into the 169 interval, then physically changes down which you can feel. The numbers stay up though in both mywhoosh and trainer road. So 20 seconds into the rest interval the pedaling is easy but the orogram reads like you’re still pushing.

I have power cycled everything. I have done the factory spindown. I have un-paired and re-paired the trainer. I have even used the non beta macos app. Same. Any ideas?
