3 of them.
1 has been around since launch. That is when you click on any item in Transactions, it takes you to a Buy page. Yet you’re still in the transactions tab. There’s no way to go back; you are irreversably in the Buy screen. Yet you can’t click on the Transactions tab to open up My Transactions again because it is currently selected.
To get to Transactions tab, you have to click —any tab except Transactions-- followed by Transactions.
The other issue is recent for me, in that I click on Items I’ve Bought or Items I’m Selling and it just sits there a while before saying “NO RESULTS”.
Lastly, items in invisible bags don’t appear in the TP sell screen. Cool. But when you move them into a regular bag, they still don’t appear. You need to close and reopen the sell page to be able to sell it. The sluggishness of the UI should really be improved, and things like this are just more needless loading delays.
