most of my Apple devices hostnames would change over time by adding a number to the end of the hostname which is incremented continuously.
Thus AirPrint stopped working reliably since the printers Bonjour name is changing permanently. I have not had the issue before the update.
Same problems here, I haven't been able to figure it out!
It should only be enabled if you have one or two way traffic enabled
I'm having these same issues with incrementing hostnames and bonjour printer access not working. Neither one or two-way traffic are enabled.
