Eingeschränkt.

On Wayland, currently only outgoing remote control and incoming file transfer are supported. If you need incoming remote control, you have to sign in with classic Xorg.

From a developer perspective, we would be more than happy to leave the archaic X11 technology stack behind and jump on the new and shiny Wayland train. However, that is not as simple as it may seem. By design, Wayland does not provide an interface to do remote control (screen capturing, mouse and keyboard emulation). This is to keep the Wayland core lean. The idea is that the compositor provides these interfaces, which could mean that TeamViewer would have to implement different interfaces for every desktop environment we want to support. This is unfortunate, but it's even more unsatisfying that these interfaces are not available yet. The closest to having something useful is Gnome, so it is likely that it will be the first desktop where we can support Wayland. To summarize: Yes, we want Wayland support, just as much as you, and we will work on it. I just wanted to let you know that it's a bit more complicated than 'just make it happen', as it is for the other features
