This has started happening for me since an update a couple of months ago. Me and my wife have a DiretoX each - Connected to different PCs. It is happening to both.
Then the ride starts the Direto makes a horrible grinding noise as if the Direto is being commanded to resistance that is beyond its intended range.
The ride then starts and the resistance is wrong by one extreme or the other its far to easy or I can barely turn the pedals. If after a bit of riding (Normally a significant change in gradient) it sorts itself out and all is good.
I have managed a couple of time to get it working by going into the spin down calibration. But this doesn’t always work.
Anyone else seen this? Is there a fix?
