Timeline shift not working

We have recently started using the timeline function, when I link a task from end to start it appears to work (shows link and the description says Blocking , FS)

However, on moving the first task up a few hours the dependent task does not shift with it

Thoughts?

Welcome, @Chris_Maxwell1,

What do you have set for Dependency management options (which is found in the Timeline tab’s “…” menu or the project’s action menu?

Thanks,

Larry
