New Mater Trophy Features and New UI on iOS platform?

Me and my mum are both huge funs of this epic game, and there is something strange that draws my attention recently.

We both play the game on the same platform, however the UI of our games are different. I’ve posted the screenshots of our phones, as you can see the events button changes its position. By the way, the games are both updated to the latest version.

Furthermore, I notice a new feature of the Master trophy that gives me extra 10% scores in every level of next episode, which is so much helpful to get sugar stars. I wish this cool scheme can apply to the game in my mum’s iPhone. Is it possible to do that?
