Wasabi has silently broken compatibility with non-free coordinators since the last release v2.0.9 by removing the free remix and friends don't pay feature. If you see "IncorrectRequestedAmountCredentials" exceptions on the client side, it is because of this. The coordinator fee will be completely removed with the next release - https://github.com/WalletWasabi/WalletWasabi/pull/13297#issuecomment-2283555140. The last Wasabi version that is working properly with non-free coordinators was v2.8.0.1.
