How to upgrade from /e/OS 1.21 to 2.0 on Fairphone 4

Clearing cache and storage of the updater didn’t resolve the issue, neither did deactivating Advanced Privacy. I also tried disabling AFWall+ and restarting the phone, but still no update shows up.
And the outage at Murena seems not to be fully resolved yet, as I understand. So maybe I’ll wait some more.
