Vocal snap doesn't work with Bluetooth in the car.

Hello, I have a little issue with the Bluetooth in my car. When I try to listen to a voice note on Snap, the sound doesn’t come out of the vehicle anymore; when I try to listen to a TikTok, the same thing happens, there’s no sound even though when I play music, everything works perfectly. When I watch a video on YouTube, everything works fine, just TikTok and when I try to listen to a voice note on Snap, I can’t do it, I don’t know why. I hope someone among you has a solution. Thank you very much in advance. PS. My vehicle is a Megane 3 2012. The Bluetooth is integrated into the vehicle and everything works properly. Just Snap and TikTok don’t work the same way. When I try to watch Snap Stories, the sound doesn’t come out. I noticed that when the music was playing, and I started a Story at the same time, I was able to hear the sound of the Story in the background. Thank you for your help.
