Xfinity WiFi Sign In Page Issues

A few days ago my iPad stopped connecting to the Xfinity WiFi. I have an active monthly pass. When I select the xfinitywifi network I’m taken to the log in page. I can successfully log in and it tells me my pass is still valid but it won’t connect to the network. Usually the sign in page has the word DONE in the top right hand corner. Mine only has the word CANCEL. I successfully connected my iPhone to the network with a complimentary pass. And my iPad connected to the Starbucks wireless network at my local store. Thoughts?
