We don't see many Bluetooth issues with the Raspberry Pi, but when we do, they're almost always caused by the Raspberry Pi OS operating system being out-of-date or simply an older version.
The quickest and easiest first step you should take when experiencing Bluetooth issues with a Raspberry Pi is to re-write the micro-SD card with a fresh copy of the Raspberry Pi OS, using the super-simple Raspberry Pi Imager tool: https://www.raspberrypi.org/software/
If re-writing the SD card doesn't work, we suggest searching the Raspberry Pi Forum for pointers and/or raising a post there for support, as we're not aware of any other known/common issues with Bluetooth with the Raspberry Pi.
