Hello,
Could you, please, numerate your questions to avoid misunderstanding when I’m answering.
So,
1) Is the issue with the wishlist solved?
2) I have uploaded the source theme and XStore plugin files and the product layout looks ok on the mobile https://prnt.sc/26epuzv
3) Check the mobile menu items now, please.
4) Filter area is closed on mobile as I can see http://recordit.co/wDj47qmquY
If you click the filters button then it displays the filters you have. So, do you want to collapse the filters? Use option Sidebar Widgets Content https://prnt.sc/26eqbm1
