Welp. Interestingly this is just about the ONLY issue I've ever had with Poweramp. That counts for something.
On the other hand, to have me appear here to say it means the issue raised its head again (Had it on Ace 3, J5 and J5 2017). It's not all that frequent... but as painful as ever to sort out. So yeah, it works again, but... it's a repetitive issue.
Just adding myself to this thread. No point in starting another one, right?
