FP3 Bluetooth not pairing

I have a new FP3. All seems to be working except Bluetooth pairing. I’ve tried on a couple of devices (speaker, watch) and neither will pair. It recognises the devices in the Bluetooth list if devices but won’t pair. Does anyone get a similar problem and / or a solution or fix to this problem?

I saw you already found the other topic Bluetooth issue: device refuses to be paired

I’m closing this one so all info about the same problem can be found in one place.
