Unable to delete subnet delegate to Microsoft.DBforMySQL/flexibleServers

Question

I have a subnet delegated to Microsoft.DBforMySQL/flexibleServers. I integrate MySql flexible server to that subnet, for test purpose. Now I delete MySQL server and I want to delete subnet as well, but azure does not allow me to do this. Please help me with problem.
The error:

Failed to delete subnet 'snet-bff-mysql'. Error: Subnet snet-bff-mysql is in use by rg-vnets-dev-we/providers/Microsoft.Network/virtualNetworks/VNET-SPK-D03/subnets/snet-bff-mysql/serviceAssociationLinks/2f92f3ac-eb85-f7ec-eca2-5f5320bde0c1-sal'>VNET-SPK-D03/snet-bff-mysql/2f92f3ac-eb85-f7ec-eca2-5f5320bde0c1-sal and cannot be deleted. In order to delete the subnet, delete all the resources within the subnet. See aka.ms/deletesubnet.
