I can also confirm this. Running a MotoX XT1053 on Android 4.4.3
Also, there seems to be some bluetooth issues going on now as well. Sometimes when I am connected via bluetooth to external speakers, if i start playing music, it will just play out of the speakers of my phone. It appears as if Spotify is not recognizing that I am now connected to external speakers.
In addition to this, now whether I have sound muted or not, when my device locks, there is a 1 second skip in music playback. Previously this did not happen.
It's early days but I have seen some grumblings, particularly regarding bluetooth, including this comment:
After updating to 4.4.3 on my Nexus 5, music routes to speaker instead of Bluetooth. I tried NFC pairing and still no success. I called Google hardware support and they said people are calling in with Bluetooth issues. He said they will track the amount of open service tickets regarding this issue and have the development team work on a fix. He said do a factory reset but I am glad I didn't b/c that doesn't seem to fix it. I had no Bluetooth issues on 4.4.2. Can't rollback to 4.4.2. I wish there was a fix
Yes, my development team has also told me that the bluetooth issues seem to be widely related to AOSP devices such as the Nexus phones and MotoX phones. Absolutely zero issues when I was using Spotify on a Samsung Galaxy S4. I was just hoping there might be something the developers at Spotify could do or maybe look into the issue.
