Ubuntu 22.04 - Time zone does not update automatically

Question

The Problem

I'm doing some extended travel, and I notice that when I change locations, the time zone does not update automatically. My current work around is to just run sudo dpkg-reconfigure tzdata each time I switch locations. However, it'd be nice to not have to do this manually.

I'm looking for a solution that:

Makes the time zone update without human intervention (e.g., I don't have to run sudo dpkg-reconfigure tzdata in order for the time zone to update)
Does not require me to install a third-party script (I believe automatic time zone updates is a built-in feature that should work out of the box without third-party help; please correct me if I'm wrong on this).

Research I've Done

Below are the relevant posts I've read that haven't helped.

timezone not updated automatically: I updated /etc/systemd/timesyncd.conf as suggested, but it didn't resolve the issue.
Auto Timezone doesn't update: my location services are enabled (see system info below) and I would prefer not to install a third-party script.
How can I make Ubuntu automatically detect the correct timezone based on my internet connection?: I would prefer not to install a third-party script
Automatically set Linux timezone according to location: I would prefer not to install a third-party script.
Would like local time to be automatically updated: The discussion in the comments doesn't have any suggestions.
Ubuntu 22.04 Auto Timezone is wrong: This question is unanswered.
Ubuntu 22.04.4 changing time zones stopped working: This question is unanswered.

My System Info

I'm running Ubuntu 22.04.4 LTS only (no dual boot), 64-bit on a Dell XPS 13 (9380).
Running gsettings get org.gnome.system.location enabled returns true (location services enabled; verified in the GUI as well)
Running gsettings get org.gnome.desktop.datetime automatic-timezone return true (automatic timezone enabled; verified in the GUI as well)

Contents of /etc/systemd/timesyncd.conf I've tried both of the following and neither worked.

[Time]
NTP=
FallbackNTP=ntp.ubuntu.com
RootDistanceMaxSec=5
PollIntervalMinSec=32
PollIntervalMaxSec=2048

and

[Time]
NTP=ntp.ubuntu.com
FallbackNTP=pool.ntp.org
RootDistanceMaxSec=5
PollIntervalMinSec=32
PollIntervalMaxSec=2048
