Home Page Tile had it's App setting blanked - why?

I have to dashboard applications: one called “HCP Dashboard” and the other called “HCP Dashboard Kinetic”. The Kinetic Home page had only one tile that pointed to the classic “HCP Dashboard” application.

After working on some related BAQ’s and the new “HCP Dashboard Kinetic” dashboard was deployed to production. The new dashboard was launched from the menu. There was NO home page tile to launch the new program. Somehow the older “HCP Dashboard” tile, that pointed to our classic version of the program, is missing the App setting to connect it to the dashboard.

Is there a way to backtrack and find out what broke (cleared) the App setting? Could changing a shared BAQ or updating the HCP Dashboard Kinetic have caused the App setting for the older classic HCP Dashboard to clear?

When I say tile, this is what I’m talking about:

Pretty sure I used to see similar behaviour if you deployed the classic dashboard and used the option to add a Favourite menu item, then subsequently redeployed and the menu item would go missing. Can’t remember the exact steps to replicate and try as I might I can’t get it to do it on 2024.2

Thank you.
We using 2022 for now. I know we’re going to update to the current version, but no one seems to know when.
