I tend to browse Pacer side by side with courtlistener, e.g. get the docket, read through docket on courtlistener, then click through to buy the documents I want. When there's a delay like that I'm never quite sure if it was actually uploaded successfully so I go save the documents separately, it's inconvenient.
Also, is there any way you could upload documents that members of a case get for free through Pacer? What I've noticed is that it'll show the docket entry if I have the extension installed, but it's an abbreviated form (e.g. "motion to dismiss" instead of a longer entry with party info, attachments, etc).
