My iPhone 11 Pro Max has issues when using Bluetooth

My phone (11 pro max) has issues when using Bluetooth. It only happens occasionally so it’s not a huge deal more of an annoyance but when I connect through Bluetooth and try to play music (through Spotify or Apple Music) it’ll play through the Bluetooth device for a few seconds before reverting back to my phone as if I’m not connected.

This happens with my headphones, Alexa speaker, and my car. My phone says it’s connected still even when it’s not working. It doesn’t matter how many times I forget the device and set it up again or even restart my phone the only solution I’ve found is to wait a few hours and then eventually it starts to work again as it’s supposed to.

Honestly, not sure what else to try but I’ve noticed it happening more frequently lately and I use the Bluetooth feature every day so if anyone has a fix for this I’d appreciate it!
