can’t change address/country

hi, I’m new to Vinted, I haven’t placed any orders yet. I am in the US, but have a VPN on my phone that puts my IP address in Finland, and Vinted assumes I’m in Finland and will not let me put in my real address even with the VPN off, restarting the app, and deleting and reinstalling it. I am also not able to put in my phone number since the area code is preset to Finland and I can’t change it. anyone know how to fix this?
