Not painting after offset

Why can’t I clone anything after using interactive to offset the clip I want to clone? Very confusing at this point. I’m following the Get started with Digital Paint tutorial where he shows how to offset image to clone using the interactive setting but after doing that nothing clones I can’t paint anything. Is there a step I missed.

Always make sure to disable the onion skin and Interactive mode to do the clone. You didn’t mentioned about this in your query. If you already did, then probably something else might be the issue.
Not sure this will help you !
