Question on Tax Documentation in the EU

Dear Cambly Tutors, I have a question for all of you. I just moved to Poland but I was born and raised in the US. I have dual citizenship. I just recently moved to Poland and when I want to login, Cambly is required to collect taxes from EU residents. Currently I don’t have a VAT ID and I don’t have a Polish bank account. I am not sure what to do at this point. Any suggestions on how I can bypass this legally?
