Cross-platform Mac/Linux/PC no longer working in Civilization 6?

Since a PC update to 1.0.1.501, this seems to have broken cross platform play between Mac/Linux versions and PC versions of the game.

Aspyr Media - the developers of the Mac/Linux version of Civ 6 - said on twitter on 29th May that:

Maya & Gran Colombia Pack is available now

This suggests an update to be inline with the Windows version, yet the bug still persists.

When playing on the "Internet" option, Mac/Linux users are presented with the error: "Version Mismatch", while playing on "Unified PC Play", an unspecified error occurs when connecting

Does anyone know if there is a workaround to force Civilization to not check the version since they are running the same build (to my knowledge)?

I found this workaround that worked for me (performing on my mac to play with windows users):

• Go to:
  • ~/Library/Application Support/Steam/steamapps/common/Sid Meier's Civilization VI/ on Mac
  • ~/.local/share/Steam/steamapps/common/Sid Meier's Civilization VI/aspyrassets/global/string/app.json on Linux
• Change the following lines:

 "App.WinFileVersion" : "1.0.1.501", "App.WinProductVersion" : "1.0.1.501", "App.WinFileVersionStr" : "(504666)", "App.WinProductVersionStr" : "(504666)",

It goes without saying that this can lead to unexpected errors. (I didn't notice any.)
