I have base model M4 mini on Mac OS 26 which keeps removing the docked application launcher. I keep adding it back which works till the next incremental update and it's been removed again. The ONLY way I can stop this from happening is to create an alias to the folder and to add that to the dock. I have 3 devices on the 26 Dev beta and the other 2 do not suffer this issue. I was expecting the release candidate to have resolved this but alas it hasn't.
