I have been playing with 3.9.3 for about a week now. Mostly it seems all ok but I find every now and then I’ll transition to the next part and the screen will display transition but then just stay on the same part. It is very random so doesn’t do it in the same places all the time. I’d consider myself pretty efficient in using the BB so I know it’s not when I’m pressing the button. I’m a little concerned that it is actually displaying it is transitioning but then just stays on the same song part.
As I said though, it’s very random. I have gone over and over songs where it’s happened and never got it to happen again. I will keep playing with it for now but might have to go back to 3.80 if it keeps happening.
