On-Player Triggers with Variables not Working

I've created a story file that has a 'home button' on the player itself, sending the user back to the home menu if they're in the training.

At the beginning of training, there is a welcome video which we don't want them to skip by clicking Home. After the video, the variable adjusts to true and the Home button is then 'live'.

This works in Storyline preview mode AND when played locally, but it doesn't work when uploaded to SCORM Cloud. Has anyone experienced this? Killed about an hour troubleshooting...

The output is 110 mb and I don't have a ton of time to replicate with a test file, or I'd share.
