Yesterday i've tried LibreELEC-RPi5.aarch64-12.0-nightly-20231219-865d980.img.gz on my RaspberryPi 5 and i had to find out that i can't connect my Sony PS3 bluetooth remote. I got always asked for a pin at the first buttonpress after establishing a connection, no matter how i connect it (trust and connect/connect). I removed and disconnected it multiple times and added/connected it again with the same results.
I'm now back on 11.0 (LibreELEC-RPi5.arm-11.0-nightly-20231218-f33f513.img.gz) and the remote works as expected (with trust and connect).
