I played around with this some more & have more info.
I created a playlist that has my four main stations I listen to in it, copied it to my phone & opened it with a file explorer app which allowed me to then open it in XiiaLive. All four stations were present in the playlist now & hitting the back/forward buttons advances through the playlist. So from what I can tell, in IOS the back/forward buttons advance through the playlist whereas in Android it advances through the favorites (or maybe both if there are multiples entries in the playlist?). The workaround is better than nothing but still sucks because if I ever manually play a station from my favorites I have to go through all these hoops to get my playlist loaded again.
Not sure if you guys changed anything yet but I was able to upgrade to Pro about 45 minutes ago without any issues this time.
