ERG almost impossible to peddle at beginning of ride

When I finish a segement of FTP builder, sometimes on the next ride, the Wahoo Kicker is impossible to turn over. I have to lower the 100% setting to 90, then everything is fine, and I adjust back up to 100% Thoughts?

Hey Jay, do you happen to have your Kickr paired to your Wahoo app? Can you close Zwift then check your Wahoo app and see if you can unpair? Then go back to Zwift and pair your Kickr again. Let us know if anything changes!
