I have implemented a basic version of progressbar.js when a user clicks save.

A bar moves across the screen as a visual indicator.

However, it is not directly tied to the save progress.

When a user clicks save, it moves across to 50% over the course of a few seconds and as soon as we have confirmation from bloxby it zooms to 100%.

The problem comes when sometimes it takes a long time to save a page, the bar stops at 50% and hangs.

So, how can I tie this directly to the actual progress of the page saving?

Where is this function located, any clues would be super helpful.

Thanks!
