I'm being billed at least $50 a month for a virtual network which I don't use and am unable to delete. It appears the issue is a subnet is assigned to Microsoft.DBforMySQL/flexibleservers. If I try to delete the subnet, or assign the subnet delegation to none, I receive an error.

Thank you for reaching out.
I understand you are unable to delete the virtual network which has a subnet delegated to Microsoft.DBforMySQL/flexibleservers.
In order to determine the further troubleshooting steps, can you please share the exact error received? Thank you!
Yes, here's the error. Thank you!

In order to delete the subnet, delete all the resources within the subnet. See aka.ms/deletesubnet.

If I try to edit the subnet I get this error:

Thank you for getting back and sharing the information above.
I think a support request will be required here to remove the subnet delegation and to delete the Virtual Network.
Could you please send an email to azcommunity@microsoft.com with the details below so that I can enable a one-time free support ticket for you in this case.
