Hi there Schifter, Gabriela
Thanks for using QandA platform
Weird but that might be due to a UI issue, browser cache, or permission restrictions. Try clearing your browser cache, using incognito mode, or switching to a different browser like Edge or Chrome. make sure your account has Owner or Contributor access to the subscription. If the portal still fails, try creating the service using Azure CLI:
az search service create --name <your-service-name> --resource-group <your-rg> --sku standard
Also, check Azure Service Health for any ongoing issues. if nothing helps raise a Azure Support req.
If this helps kindly accept the answer thanks much.
