Welp, I downgraded from 13 back down to 12. I don't know why, but today when I was taking screenshots, I noticed that no matter what book I was in, it took 30 second or more for a shot. And this was on both the 950 and the 350.
I downgraded back to 12 and the screenshots are much more reasonably timed now. I hope that helps with ya'lls development. I really appreciate PRS+.
