Hi @Chap

Sometimes, using the Azure CLI can provide more accurate information and force a refresh of the Azure state, please use the below AZ CLI command:

az network vnet subnet list --resource-group <resource-group-name> --vnet-name <vnet-name>

Verify that the subnet is indeed gone from the list or if the subnet is still listed, try to delete it again using the CLI by following the below command:

az network vnet subnet delete --resource-group <resource-group-name> --vnet-name <vnet-name> --name <subnet-name>

ARM locks can prevent resource deletion. Check if there are any locks on the virtual network or the subnet level by following the below command:

az lock list --resource-group <resource-group-name>

If you find any locks, remove them using the CLI the below command:

az lock delete --ids <lock-resource-id>

Additionally, please try clearing your browser cache, history, and cookies. Alternatively, you can use a different browser and log out of the Azure portal, then log back in and reproduce the issue.

Note: Kindly try to check other subnets within the Virtual network, which might contain the Azure Virtual Network Gateway.

I hope this has been helpful!
