My Question or Issue

Wireless AA on a 2025 Mercedes with latest updates.

Spotify audio will randomly stop, while progress bar continues on. The audio will recover if I hit pause, wait 4s and hit play again. Rarely, it will recover on its own after several minutes (5+).  Repros with streaming and downloaded content. No issues over wired connection. No stuttering or other issues (wired or wireless). For a while it seemed like maybe specific incoming notifications might be causing the interruption/cut-out, but the issue repros even if all notifications are muted.

Iphone 15 Pro works flawlessly 😞

Heres everything I've tried. I'm reluctant to do a full wipe/reset of the phone because it would be pretty disruptive for work.

1. Spotify app
   1. Disabled battery optimization
   2. Allowed background activity
   3. Reinstalled/Cleared data & cache
   4. Repros with streaming & downloaded content
2. OS
   1. Enabled Battery High performance mode
   2. Muted notifications
   3. Tried RAM expansion feature (Device RAM is 16GB)
   4. Disabled Live Alerts (all apps including Spotify)
   5. Android Auto (13.7650624-release)
      1. Cleared Data/Cache
      2. Enabled Background data
      3. No battery/power settings to manage
   6. Wireless settings
      1. Cleared Cache
      2. No battery/power settings to manage
      3. WiFi connection to the vehicle doesn't seem to have any properties that can be changed.
   7. Developer mode
      1. Enabled Wi-Fi scan throttling
3. Vehicle
   1. Re-paired device multiple times

Things I haven't tried

• Different vehicle
• Different audio app

Would be willing to take a device trace (via developer mode) if that helps. Thanks in advance!
