The only thing I can think of is that you didn't set a "legal" deck that was made after the fixes.

OR

One bug I haven't fixed, when you challenge somebody, it lists everybody as a challenger, which means if you click on somebody that didn't challenge you, the challenge fails.

If you could diagnose it, got to the lobby and press F12 on your Keyboard and go to "console" tab, then try to accept a challenge and look at what the console says.
