The non-water based sealer does magic. I fixed a leak in my roof with this and painted it over and it’s done.

I remember having the same problem a while ago until one of my friends opened my eyes, and told me how to fix this. Indeed it helped to press the repeat button until the highlight is gone, and for some reason, it took me a while to discover that. It's not the best interface I would say, and shortly after I upgraded to an iOS 11. It was a headache especially when I was working out because I needed to stop very often and change the track or listen to it over and over. I had a great playlist from https://mp3juices.red and I was so mad that I couldn't enjoy it properly. The iOS 11 is much better but it's still missing some features, but at least, I don't have this problem anymore.
