Can't deploy private Azure marketplace offers - Invalid argument: uiDefinition

Until recently we have been creating and testing private offers in the Azure marketplace. As of yesterday, all 7 of our offers are now showing the message "Invalid argument: uiDefinition" after clicking "Create" on the listing page.

In addition, I can see in the browser console log that there is a 403 authentication error, when requesting the artifacts from: https://catalogartifact.azureedge.net/privateartifacts/.../Artifacts/createUiDefinition.json This happens in both Chrome and Firefox. A colleague of mine is also experiencing the same problem so I believe I can rule out a change in my subscription.

Is there a problem in the authentication flow happening in the azureedge server?

    It looks like MSFT has resolved the issue or reverted the changes implemented. I can confirm my Solution Template is functional again.

    We get the same error for a few days. Is there any documentation provided by Azure to address this problem? It seems like many users are experiencing the same thing.
