After reading G-Can's, I took a quick look of the reviews here:
play.google.com
I got the impression that most of the issues were to do with connections, that could be mostly due to people's network connections. I don't have such issues, might have been a few in the beginning but not the later versions after multiple updates that must have fixed a lot of the early bugs. However, I had my Denon, and Marantz prior, hardwired, so that might have helped.
Regardless, the Android app store shows +10K downloads, not sure how many on the Apple IOS side, so there bound to be a lot of issues reported when there are so many users, and again, most probably were from the early days before the first several bug fix updates.
