when ordering multiple simultaneous triggers on mobile, the way the triggers fan in the interface (left in front, see the image ordering underground mortuary and tireless provisioner) is different to the same interface on desktop (right in front, see image ordering hedge maze and courser of kruphix). I think it's pretty clear that them being different is an issue as it makes it harder for people who use both versions interchangeably, but I personally think that the mobile interface is unintuitive, as the fan direction is reversed when compared to how they end up on the stack. to me, when reversing the direction of fanned cards, I would preserve the front to back order, rather than the left to right order, which would result in a reversal of the fanned cards when moving between the way they are fanned while choosing the order on mobile and the way they sit on the stack.
