My 8 Flip will not find my Bluetooth JBL speaker or my Sony WH-1000MX4 headphones. If I have a pixel 6 next to the 8 Flip, the Pixel is able to see the devices. On the 8 Flip they simply do not appear as discoverable. I can successfully pair my phone with my car, using Bluetooth.
I've even tried factory resetting the phone.
