That has happened to me a lot with them. Like others, if it gets too close to the due date, I cancel the application. In the past, I've had them approve an application too close to the time it's due.
I cancelled three yesterday. I wonder if it all the same type of shop we are waiting on. I applied for four of the same type on Monday and they just say there until I cancelled them (one for some reason had a later due date so I left that one there).
On Wednesday I applied for a different type of shop with them and it was accepted within hours.
