Creating Workspace in DevOps with SPN leaves workspace inaccessible

[travis-hofmeister-quisitive]

I have created an ARM Template/Parameter files that deploys the workspace. After deploying using an SPN in DevOps, I get the error: "You need permission to access workspace" when trying to access the workspace. I am configured as the Active Directory Admin on the resource, and owner of the resource in Access Control. Firewall rules allows all IP addresses.

Using the same exact ARM Template/Parameter files, but deploying using the Azure Portal leaves the workspace in the correct state. I am able to access the studio as expected.

The SPN that deploys the ARM template has been granted the Subscription Owner role.

I can not detect any difference in what has been deployed.

Is there a known issue with deploying Synapse with DevOps / SPN?
