Had to buy it again

I used this app for years. There was a rebranding and I could no longer install it on a new iPhone, so here we go - double or nothing. Developer did not answer my email, I hope he is well and continues to develop it, maybe update the interface with new colors/graphics, make it safer to import / export bookmarks/notes (in a playlist?) I lost notes a few times... fabulous essential app for me even as it is.

Great but one really annoying bug

Love the app but it has an annoying bug. If the app isn't the currently open one, sometimes the app will lose "audio focus" and apple's Music app will displace it as the currently active audio, even though I didn't switch to Music or even have it open. I haven't noticed this happening with other audio apps I use like Audible. Please fix
