Tracking finickyness when uninstalling pre-installed apps (which has an update in overlay?)

Despite our effort in !21 (merged), we apparently still seem to have some finickyness around "uninstalling" pre-installed apps. This issue is intended for gathering various logs around this.

For those that encounters by this, please take some time to collect some info by running this command:

ls -lh /opt/click.ubuntu.com/.click/users/*

After which the issue could be worked around by running this command:

sudo rm -f /opt/click.ubuntu.com/.click/users/{@all,phablet}/<click package id>

(<click package id> can be found by finding the app on Open-Store and look at the URL, or by inferring from the output of the above command, looking for the entry with -> @hidden)
