Hello! Thank you for the bug report. It looks like one of two things is happening:

1. Your tmux -V is different than your command tmux -V -- could you validate what version of tmux command tmux -V returns?
2. Our comparison logic could be at fault. I tested our comparison logic with 3.2a and it seems to be working as expected.

If you have a ~/.warp directory on the remote machine, try removing it and see if this resolves the issue. Otherwise, we're contemplating whether or not we should be running command tmux vs tmux at this point of time anyways.
