MyKNX language settings

Hello. Is there a way to force MyKNX portal to operate in language preferred by me, not selected by my regional settings? When i sign in into the portal i see main page in English language, but after clicking "Support" in menu, i get Polish language version of the support site which is very very poor in content compared to English language. I have to change language by modify link in address bar but i have to do this each time. Its tiring and annoying.

Thanks for any hints.
