I wanted to take advantage of the new crop-coeefficient settings and tried to move one zone out of a Flex Daily schedule to a new schedule. Using the web app with Chrome (yes, still Windows 7), it shows that I removed the zone from my original flex schedule. But when i try to set up a new flex daily schedule, it says "All zones are already in a flexible daily schedule". Went to the IOS app, and I can set up the new schedule with that one zone.
After setting up the new schedule with IOS, I went back to the web app, refreshed it, and the new schedule shows up just fine.
