Anybody else has Bluetooth issues on your Windows 10 mobile? Please try the following to recreate the issue showed in my phones:
1. Transmit music via Bluetooth to your car stereo, headphones or speakers.
2. Once you are hearing the music, open Facebook up and navigate (open images, enter to other user's profile).
3. Open whatsapp up, navigate opening some different messages, send a big video.
If you followed the previous steps and the music sounded intermittent, we have a big issue that Microsoft has not still fixed. If not, only my phones are broken (rare), comment as well.
