Just tried the latest Beta version. Wanted to give the new “Copy Settings and Events”, I had a mosaic with 4 panels, The first panel I set all the events and settings and used the Copy settings and it worked like a charm.
But then I noticed I had forgot to reset the progress in the first target, went and did that, tried the Copy settings and events, and the events (other three panels) no longer show up in the list!
tldr; Once you apply it, you cant apply it again!
