Same situation for me. I don’t have any experiences with VPNs, as FS2020 runs smoothly without it. I really hesitate to buy a VPN cause it’s not easy to set up with the router. Won’t blame Telekom Germany alone, I think MS/ Asobo has to offer a solution for this. It’s just not playable!
This is how it’s looking. Nothing more is loading regardless of how long I’m waiting.
