I decided to sell them because they still have some value but I don't really want them, especially with what the company has done recently.
However, I wanted to set them up again to make sure they work. I spent hours trying to get them to set up again with no luck. I'm sure this is exactly what other users are experiencing. The old app was so nice and reliable. I don't have an opinion on the new app because I just literally can't get it to connect.
And I know they're not dead. One has an audio-in jack and still plays. It works great. There's no reason any of them shouldn't be fine. The only thing that changed was the app. I just want to get them set up so I can sell them on Marketplace for a good price as fully working.
