When you're browsing the Auction House or other item lists, if you scroll down a list of items and you click on an item, and then you hit the back button to go back to the list, it will *sometimes* move you all the way back up to the top of the list and not keep you where you had previously scrolled to on the list, so then you have to spend another 5 minutes scrolling all the way back down to where you previously were on the list. It makes me scared to click on items in really long lists because of this. Sometimes it hesitates on your spot on the list before it jumps you back up to the beginning, and I try to hold it there but it frequently makes you go back to the top of the list. This is the #1 most annoying part about the mobile app for me. Please fix it!
Side note: If possible, I will try to figure out what separates the times it does not auto-send me to the top of a list and the times that it does, and I will post that here when I find out.
