Visualize Saved Changes That Are Not Yet Effective

Think of a list of entries in the UI that can be ticked/unticked and saved. It takes some time (seconds to minutes) for these changes to become effective, so without altering, a reload of the page wouldn't show the changes.

I am wondering what is the best way to alter.

1) Fake state: We know what should become effective soon so we fake it

2) Hide: We don't show the list while things are not yet updated

3) ??? Something cooler?
