Problem

The tags you remove from your Azure cloud resource do not propagate correctly to your workspace compute resources. The tag is still present in the workspace compute even after a restart.

Cause

There is a synchronization failure between the cloud resource and the workspace compute. 

Solution

Manually edit your compute resource. Perform a minor, temporary change such as adding a dummy tag or a small change on the cluster name. 

1. Navigate to Compute in the sidebar. 
2. Select the impacted cluster. 
3. Click Edit. 
4. To make a tag change, scroll down to the Tags section. 
5. Add a temporary tag or change the value of an existing one and then change it back.
6. Click Confirm at the bottom of the page.

Alternatively, to make a name change, in step 4 instead of scrolling to the Tags section, click in the Compute Name field and make a minor change, such as an extra space at the end. Continue with step 6. 

The compute-side change forces the tags to synchronize with the cloud resource and reflect the correct tags.
