I have the same problem…

This is what I experienced while trying to load the app a few weeks ago. At that time the developer had egregiously suspended my account for 12 hours. The issue resolved when the ban expired. Perhaps your accounts have likewise been frozen.

This has been happening for over a week. Ludia dont seem to be able to help. I occasionally manage to log in but as soon as I try pvp it does not start the battle. When I close and reload I can continue fight in progress, then I am back in the error screen. Shame I enjoyed the game.
