Chris,Thanks for the update! Don't understand why the main part of this can't be fixed quickly. They don't seem to have an exhaustive update testing process!
I won't gum up the works any worse with an additional ticket unless you advise me to do so.
So. I was finally able to reach one of my "trusted" IntelliCenter guru's over at Pentair.
He remoted into my system and replicated the SCHEDULE page issue.
He kind of confirmed that they (software/server guys) must have "broke" something (no kidding ) when they last updated the Web-Client (Web Client Version: 1.044 b1 January 30, 2020).
He is elevating the issue and cc'd me the email that he sent, so maybe we will see a "fix" sometime soon.
That's about it for now.
