I'm starting to think they're not even aware of how many people are affected by this issue. I've sent in a couple requests for help, and I just received a response to the first one I sent in a few weeks ago that said:
"Thank you for the message. Please delete the WGT App from the Applications Folder on your Mac and then use the link here: https://m.wgt.com/install to download the Mac version of the game by selecting the Play on Mac button and not the App Store button. Once the DMG is downloaded, open it and then drag the WGT App to your Applications folder and then unmount the DMG. You would then launch the game from your Applications Folder."
This solution is just directions on how to install the game, and it does nothing to fix everyone's issue. It's concerning that they're still at the stage where they think this is user error, and they haven't begun to fix the actual problem with the install, but maybe this is the start of them looking into it.
If they get back to me with a real solution, I'll post it.
