I got this app to play Roblox and make the YouTube video at the same time but it doesn’t work

I’m glad this app acutely works, iv been trying to find something like this that will let me okay a YouTube video well being able to use the browser and it’s nice that it has some built in app too. All the other apps I’ve tried just won’t let me play YouTube and do literally anything else so I’m happy this dose, it is basil just two browsers split but that’s basically what I was looking for any way I just hope they add some better control with moving around in the application for example I’m watching a YouTube show and I also have Instagram open and I’m trying to use the dm to message me friend back but it won’t let me zoom out enuff or move that part of the screen where the messages are over to the middle to I’m unable to read there message. But it’s okay for what it is I appreciate an app that acutely works and doesn’t lie about what it is or cost money with what it’s offering rn

I enjoy this app,but I can’t watch two YouTube videos at once. If you could fix that or tell me how to, that’d be nice.
