Login Unavailable (Web App)

Cant get into web app even after playing the game. Done everything and still not working (unlinked xbox account, so that only pc account is connected, logged back into the game multiple times and tried the web app afterwards), HELP!

When ever I got to change to my main acc (pc) it says this and logs me out, how do I fix this?

I am still having this issue. I can login to the Companion App on my laptop, but not my iPhone. Any fixes for this yet? Played about 20-30 matches of Rivals already and played on my PS4 since 2017. Frustrated.

me too, I contact the technical service and they do not understand the error, they say it is the fault of the market, but the problem is the login.It is very frustrating that after 100€ nobody helps us.
