Yes the max limit is 50

I'm on android and not IOS so I don't know how the interface is there, but I noticed a little while ago at the bottom left on the screen when your selecting your cards to use for upgrade fodder. There is a box and when selected you can choose to select all R1 or R2 and 1 on the page. Keeps you from having to select everything on the page.

Makes life a lot easier when selling/upgrading
