I'm trying to get into the old "Good question" shop to move items and collect profits but I can't access it. When I click on my Doll Playground from my profile I can access the shop no problem and it is an old shop. However, I can't do the same for my other, bigger, old shop "Good question". I'm getting a white screen. Please help.

You can only get into your old shop with the drop down menu on top! :) Commerce -> Your Shops -> and then click the one with the exclamation mark in front of the name to get to the user interface of the shop

Thank you so much. :)

locking this up as it is not a bug!
