I'm having issues with running a Cache invalidation (i'm getting failed status everytime) and I'm also trying to activate the SuiteCommerce Base Theme, or any other Theme and it's not rendering after the activation.

Is this a newly setup site?

nope, it's not really new. It was working with a custom theme based on the Summit in Sandbox, and when migrating it to Prod we started having these issues.

Does the activation complete w/o error?

Yep, the SSP is deployed. I'm noticing that all activations finish without any errors. But for example, when activating the Summit is not rendering the theme. It's only working whit the SuiteCommerce Base Theme.
