Hello everyone

I'm new to the community, but I figured asking you all a question about VFS global, if you all have gone through it, would provide with the peace of mind that my fiancé and I need!
So here's a little back story:
My fiancé lives in Scotland. We're planning on getting married in the States in April, and submitting the application (along with the supporting documents) for a spouse visa.
So my question is this: What would our average wait time be if we paid for the expedited priority service (VFS Global, which is offered by UKVI Sheffield) in the month of April? In other words, for anyone who has submitted their supporting documents/application around April, approximately how many days did it take you to receive an answer?
Thank y'all for the time! I hope to hear from someone soon.
