Viewing purchased items

I hope that someone can assist me. I am new to Adalo and was working through the videos relating to building a cart, confirming purchases and indicating that a status is Paid. This all works, but I am having an issue then to go to My Profile for the user and to view all the items that have been purchased. When I try to link to a database category it seems to send me through endless loops and not allowing me to select what I want to link to. Is there any tutorial on how to move beyond the Cart or can anyone give any tips?

Thank you
