As of last Thursday, if you have a script open when you open play solo, Studio will not refocus to the game viewport.
I’m unable to reproduce this on a baseplate, but testing in Robloxian Highschool, it happens 100% of the time. If a repro is necessary, please message me privately.
I can add onto this - I have a test file that is just a baseplate (with 2 small aircraft on it) where this happens. This does not happen every time for my case, but it has happened multiple times before.
I can confirm this I was thinking it is a change Roblox did not a bug is happening for a while.
Basically when you play inside studio and your window is focused on editing a script the window won’t focus to the game until you click on it.
Sent a direct message with my information, hope it’ll help!
