"Schedule Change" did not update Start and End dynamically in the Info Box

[Berto2002]

I think the Change Scheduled From and Scheduled To date/times should update dynamically in the Info Box after pressing the "Schedule Change" button (and updating the timeline); but it didn't for me today. From a second one, I think it's the times that don't update but the date does, perhaps.

I needed to refresh the Request.

We have not been able to reproduce this internally, all values are updating as expected for our development team.

It's quite possible that this was the browser that needed a refresh rather than Hornbill, as that's what a browser refresh is doing behind the scenes. We are seeing slightly more of these kind of comments as browsers ever more aggressively sleep tabs in order to reduce memory usage and power consumption.
In general (not just related to Hornbill) I tend to assume that if a simple F5 resolves the problem it's the browser, if it takes more than that I start to question the page/site/application.
