Saris h3 delayed power

I have seen this before but since the update last week my saris h3 trainer is lagging behind on terrain/resistance changes. Like when I hit a downhill all of the sudden I have the resistance of being on the hill that I just climbed… all was fine until the update. I have recalibrated via the Saris app 3 times to no avail. Running Zwift through my iphone via bluetooth connection to the Saris H3.

Any fixes?
