Known issues:

If your connection is lost, when your device suspends, try the following options:
- Go to settings and set option "Stay awake" to avoid standby mode
- In your Wi-Fi settings set "Keep Wi-Fi on during sleep" to "Always"
- In your Wi-Fi settings deactivate "Wi-Fi optimization"
- Connect your device to the power adapter while using SoundSeeder to prevent standby mode
2) The automatic discovery of SoundSeeder Speakers / Players does not work on some devices, while they are suspended:
- Activate the screen to wake up the device and restart the device search.
3) The playback of SoundSeeder is asynchronous or lacking:
- Check the Wi-Fi signal strength and traffic load. A dedicated portable HotSpot or WiFi direct might result in a better performance.
- Pause and restart the playback of the SoundSeeder Music Player to sync the playback
4) Playback via Bluetooth Speakers is not in sync:
Bluetooth speakers add a delay of 50ms-200ms to your music. This delay can vary, each time you start the playback. Therefore a synchronized playback via bluetooth speakers is not granted!
