How to force an app to change screen orientation from Portrait to Landscape?

[tech_clash_2007]

Does anyone know how to force an app to change screen orientation?

From portrait to landscape and vice-versa. 

I don't what to download anything and program anything. 

I am using a Samsung Galaxy Tab S7.

• Go to the play store and download Rotaion: Oriantaion Manager. I had the galaxy tab s9+ and now have the galaxy tab s10 ultra and the only thing I've ever seen it not work on is reddit. No clue why, but I'll get that, too. Oh! I forgot to mention that it's free.

At first I wasn't sure if I should post. I figured 4 1/2 years is a long time, it'll probably be a useless post. I'm glad I could help. I know the frustration of knowing there has to be a way, why can't I find it.
