Wrecked my ride! Twice in a row!

Come on, Zwift. You must do better. Twice in a row you wrecked my Training ride with random and out of synch ERG swings. WTF!!! Fix this. It happens sporadically.

I recalibrated my Saris M2, restarted it and the Zwift PC program. I even change nothing and simply restart the program and it will work for about 20 minutes then suddenly it starts randomly changing ERG, then disabling it and restarting it, only to annoy me once again in 60-90 seconds.

DO BETTER!
