Cannot delete VNET, Gateway stuck in backend?

So of course I am aware that Central US had an impact on the Azure Resource Manager so it may have been my redeployment of a Virtual Network Gateway yesterday that created my current predicament.

So since the Azure Resource Manager should be back up, at least it is answering to my input,  I thought I could start a cleanup of my test resource group, but I cannot delete my GatewaySubnet.

I cannot see any resource, including no Virtual Network Gateway blocking the resource (Listing Virtual Network Gateways in the affected resource group just returns [])

So since I cannot delete the subnet and no gateway is left, I went on troubleshooting the VNET deletion with Azure Resource Explorer. I can reset all the resources to provisioningState "Suceeded" however I will not be able to delete them.

Why am I suggesting that there is a gateway stuck in the backend?

Well deploying a new virtual network gateway to the affected resource group returns the following error:

"The resource operation completed with terminal provisioning state 'Failed'.
"GatewayModeRequirementNotMetForCoexistence\"
"Operation failed for virtual network "VNETNAME" as only one Dedicated and one DynamicRouting gateways are allowed in a virtual network."

 az resource list -g RESOURCEGROUPNAME
[
  {"id": "/subscriptions/SUBID/resourceGroups/RESOURCEGROUPNAME/providers/Microsoft.Network/virtualNetworks/VNETNAME","identity": null,"kind": null,"location": "westeurope","managedBy": null,"name": "VNETNAME","plan": null,"properties": null,"resourceGroup": "RESOURCEGROUPNAME","sku": null,"tags": {},"type": "Microsoft.Network/virtualNetworks"
  }
]

So is this still a problem with the current situation in Central US? My Azure Location is Western Europe.

Cheers,
