I can confirm this behaviour on Ubuntu 22.04.
I see the creation of an Inrelease.timestamp also with 1 client.
My apt-cacher-ng installation is upgraded from 3.3.1 to the version
mentioned in this report.
Unfortunately I couldn't find any helpfull extra information. I tried
making some changes to the config file, which don't seem to help.
