Did Airbnb confirm that they deleted account? They are using vague term “cancelled your account”. That is a fishy use of “cancel” word where “delete” should have been used. I don’t trust Airbnb.
Most companies don't delete accounts when you request to delete account, they only disable your access to account. So, before cancelling I prefer to go into account, remove as much info as possible and change all other info before requesting to delete account.
AirBnb wouldn't even let me access my account until I accepted their new T&C and upon declining they just moved me to cancel account with no chance to make any changes to existing info.
But yeah, a lot of companies don't even do what the GDPR actually requires, let alone what people think it does.
