Foreigners using Rednote: How can i post?

This seem like a stupid question but its driving me crazy. Im registering using a spain mobile number. After my account is created i can access to all function but not posting. Every time i post it just shows 0 impression: Im "shadow banned" for some reason.
I tried seeking help in the customer service chatbot but its all AI and not helpful at all. I have sent an email to xiaohongshu, but that was no use too...they created some ticket for my account (i can see inside 申诉中心) but nothing made any progress.
HELP!
