It's been impossible to play on Mobile Data for 4 weeks (but it works on wifi)

Thanks Gunner! I've posted a thread on the ISP forum to spread the word from Meathead (in French):

It is still not working on mobile data but I've found a workaround yesterday. You can play on mobile data with orange if you use a VPN. I got NordVPN yesterday, it works fine if I activate it before launching the game.

It's clearly not ideal, but it saves the day for now.
