@artisticcheese Sorry for running into this! I've been looked into it locally and noticed that in the PUT request to create the pool actually have the tags set in the request body, while after it's been created, the response body doesn't reflect that.

May I know where is the entry point to the agent pool from ACR in Portal? So that I can test what happens after I manually add the tags (the update request of the pool doesn't have the tags defined, so the azure CLI can't be used to update the tags).

You need to click show hidden types and then you can get to a pool in portal Updating through portal is not working either obviously, since as you mentioned PUT request does not allow tags.
