Ok great, that's mostly got it sorted, thank you. I've been able to get it working for standard windows programs, but it doesnt seem to work with apps from the Microsoft Store.
I had a similar issue trying to get a trigger to activate an app from the Microsoft Store once before, and another user helped me on another thread...

This seems to be a similar problem, but the same solution doesnt seem to work.
So my method is as follows...
I have 2 monitor profiles saved, '2Mons' & '3Mons'. I would like to be able to activate my 3rd monitor, and have Spotify (from the Microsoft Store) load on it. Under TRIGGERS, in events, i select MONITOR PROFILE CHANGED, and select the profile 3MONS. I then select ADD - ADD NEW CUSTOM FUNCTION. I give it a name (which i cant seem to be able to use or delete old names??), and under FUNCTION ACTION i select LAUNCH APPLICATION.
Using advice from the previous thread, under APPLICATION i put in C:\Windows\System32\ApplicationFrameHost.exe, and under APPLICATION PARAMETERS i type SPOTIFY. Then save, but this doesnt work. I'll just clarify again that it works fine with normal programs like Windows Explorer.
Would love any advice you could give
