@Amiyah7 It could be you have been 'caught' by the anti-party algorithm. If you are young, booking locally and booking an entire home this might be the reason.
Since you posted in our community a few days ago, I would like to ask if you have managed to book on Airbnb. I am sharing the link below where you can reach out to the Support Team in such situations: https://www.airbnb.ca/help?audience=guest
They will be happy to assist you as soon as possible.
