Hello,
I have a problem with the Spotify Android app while streaming songs via Bluetooth.

When I play a song, the first title is shown correctly. When playing the second title, the Metadata stays at the previously played Title, this behavior continues with every song I play (even if I skip to a specific song. It always shows the previously played song), until I reconnect my Bluetooth connection to my car multimedia system. Then the same thing happens again.

Another Bug I found with Android 8 is when I disconnect my Smartphone from a Bluetooth Device while playing music, the music won't stop and continues to play. This Happens with every Bluetooth device I own.
If I downgrade from any Android 8.x Rom to an Android 7.x.x Rom, the wrong metadata Bug is gone. Now everything is shown Correct.

After watching the behavior of the two Bug, I think something is wrong with the Android app on Android 8.x. Both Bugs occur with every Android 8.x rom I flashed on my OnePlus 5T.

If you need any more information or test done by me, I will try to respond as quickly as possible.

What I have already tried:

• Different Playlists/Radios
• Pausing / continuing the song.
• Reinstall Spotify.
• Clear Cache/Dalvik Cache.
• Reset to factory settings (Car System & Smartphone)
• Different Bluetooth Audio codecs (aptX HD, aptX and SBC)
• Dirty flash from OxygenOS 4.7.6 - Android 7.1.1 to OxygenOS 5.0.3 - Android 8.0
• Clean flash (full wipe in recovery) the above said Android 8 Roms
• Stream the music via WiFi, Mobile Data, Offline Mode
• Tested in other Cars: Audi TT(2015 model) and a Fiat Doblo (2016 model)

What I cannot try:

• Test with another Bluetooth Device (I have no other Bluetooth receiver with a built in display)
• Test with another Smartphone (none of my family/friends have a smartphone running Android 8.x)

What helped / solved the Bugs:

• Downgrading to Android 7.1.1 (Official Rom - OxygenOS 4.7.6)
