Nvidia Shield Pro 2017
**Steps To Reproduce:**
Send invite through steam menu and unable to accept due to an unknown error on both the sender and receivers side. This doesn't apply when I do it from my PC.
I don't know if this is a steam error or not. I can access just a basic multiplayer game without any invites and play there or by myself, the only errors come up when invitations are send on the shield platform.
Something that could solve this issue would be creating a lobby for you to select custom multiplayer games instead of just getting out into one.
Do note that Generation Zero was developed for Win 7, Win 10, Xbox and PS4. All other platforms, including GNU/Linux and Nvidia Shield are incompatible and you can face issues using unsupported platforms.
