UPDATE: I figured it out. If you go to Purchased Items and look to the right, there will be a check box next to every item. It's much easier to find on PC than mobile.

@KhareemPai thanks. I literally was searching forums before asking the same question... I'd favorited things before but couldn't find it. I think it doesn't show the full page on mobile unless you enable "desktop site" in your browser. I had the same issue

@KuroNoRider Glad I could help! It was pretty annoying to find out how to do it. The only mention I found was from the last paragraph of one of TD’s posts. I figured I should leave this post up to help others like yourself.
