I just got a new phone yesterday, so I don't know if this is a "me" issue or a Tapatalk issue or an UCP issue. I can pull up Tapatalk and sign in no problem. I see the UCP forum. I click on it, it shows blank. When I click on the button that pulled out the side bar so I could pick whether I want to read "unread" or "subscribed", etc. I get the message "connecting to server" and it just hangs indefinitely. Going on 10 minutes this try. It's a Galaxy Note 3 on Verizon if that helps.
