Have not personally experienced it myself, but have heard about other Hosts who have. Many times it is an issue with the requirement that the name and address on Airbnb EXACTLY match the STRA registration info with the governmental agency.
Other issues result from a Host allowing a registration to expire. Then when attempting to add the updated registration, they run into all kinds of issues (BTW, never let your registration expire to avoid this).
Thats all I can think of at the moment...
