Duel not working- "No Connection"

When I try to compete in Duel, it says “No Connection.” When I tap “Retry,” it doesn’t work. Anyone else have this issue or know how to fix it?

Do you have service, If so I don’t now how to help that’s my only explanation🤷🏼‍♂️

I have the same problem. I uninstalled and reinstalled and it still happens.
