Hi, thanks for the quick reply! Unfortunately, this is my only production machine for work and studies, and I cannot risk the instability of a Release Candidate (RC) kernel right now.
Is there any other specific log (like dmesg, journalctl, or hcidump) from my current stable kernel that I can provide to help investigate this BlueZ/hardware handshake issue with the JBL Flip Essential 2? Thank you for your understanding and for the great work on Ubuntu!
