Light and heavy resistance

[bob]

I have had my Suito for a couple years with no issues. For the past couple of weeks the resistance is either very high or very low when using Zwift. Seems worse when doing intervals. I have the same problem whether I use my iPhone or iPad and both are up-to-date. I have unplugged the unit, did a short ride with the elite app and made sure Zwift is updated and calibrated. Could it coincide with the last update in Zwift?
