I'm on Apple and I have to open the Alexa app two times every time I try and use it. The second time it actually opens. The first time it opens and shuts like it was exited by me... flashes up the home screen for a micro-second then back to the phone's home screen. I use it to shop for the list capabilities between home and multiple [hones, so it's a bit aggrivating at times... but I muddle through.
