Canceled reservation with no explanation

I am a first-timer to use Airbnb and they just canceled my reservation yesterday (22/02/2025), which I made at the beginning of February, with no explanation of why it was canceled.

They say the refund is on its way and would take 15 days to reflect on my side. Why do they cancel with no explanation? This is so frustrating as one has to start looking for accommodation in such a short time.

I do not recommend the use of Airbnb to anyone. it just brings fustration.
