Priority service receipt question

I saw that I'm supposed to provide a copy of the priority receipt with my application, but I can't figure out if I actually have one or not. The document checklist and application mentions it's a "priority service". Is that what they're talking about or should I have received something else? I bought priority processing through the UKVI application process, not the VFS website and my card was definitely charged the fee.

Hey! Just wondering if you ever found out if your application was processed as priority from paying on the gov.uk site and not VFS Global. I'm in the same situation of not having a priority receipt but just an email confirmation of the 738 I paid at the end of my visa application.

Any updates with what happened with your application?

Bit stressed as I haven't found any information.

Thanks!!
