ipad pro will not connect to Xfinity Now wifi pass

My ipad pro gen3 won't connect using my Xfinity NOW wifi pass. All my other devices connect just fine. I only have one device connected and I've tried to resetting the network settings on my ipad, to no avail. I have also tried turning off private wifi address and limit IP address tracking and that didn't work. I was going to try to turn off automatic date/time update to set the date back to 1970, as I'm told this solves some network connection issues, but it says I can't because of device restrictions. I tried resetting location and privacy and still don't have the option to turn off automatic date/time update. So I'm at a loss as to why my ipad can't use the Xfinity NOW wifi 30 day pass!? Has anyone found a solution for this issue?
