The same for me and several people from my league. Seems to me that the problem is once again somehow up to Russian internet restrictions and bans, because I'm in Russia atm as well as those people from my league who have same issues with the app.
Yeah, it works through the VPNs but it only helps when you need to do simple things like prepare for the race or reply someone. Race viewer and participating in auctuons is a huge headache as VPN connection can be unstable especially when every second counts and every moment of your absence due to bad connection can cost you a lot.
The problem is still unresolved. Sometimes it works, sometimes it doesn't. Today it was so bad, that even VPN didn't work out for several minutes after the race.
