Chromecast support now seems to be very intermittent. I'm using v1.56. Needs an option to prevent it using mobile data, it's used my data allowance when the WiFi dropped out. Downloads fail a lot, and the app seems to have got very slow. After some updates of my phone and sounds the download function works again, also the quality option is back, and wow the high quality downloads sounds so much better than standard. Otherwise I still find it cumbersome to navigate.
