Mecool M8S Pro Help needed

[homenet]

I have a Mecool M8S Pro box. It had a Youtube icon on the startup screen. Today I clicked on it and it said need to update, so I clicked update but then Google Play store said that the version is not compatible to my device and removed it.
I then went into Setup>apps and found the Youtube there. I clicked on it and it worked but it does not show in my Apps list on the startup screen.
How to put it on the startup screen?

Thanks.
