I just got my license today. Requested it yesterday. A little inconvenient to delete a file in Android. But I'm curious why the play market rejected their updates. It sucks, that platform worked well, and I'm sure their current licensing solution is a hack workaround.
I would definitely recommend using Android. The Windows app doesn't work well on all computers and isn't supported or updated. I have a collection of 38 different versions someone provided me with when I was troubleshooting it though if you want to try your luck.
