As recently communicated, Google Forms is in the process of upgrading older forms to the new version of Google Forms, followed by the auto-upgrading of legacy themes to allow for customization and a better mobile experience moving forward.
After the theme upgrade, some text and colors from older forms may not show up properly, in which case Forms editors may want to choose new themes for their affected forms.
Starting today, people working with affected forms will see a notification alerting them that their current theme is no longer supported and encouraging them to choose a new theme.
The legacy theme upgrades will happen on a rolling schedule starting in about 2-3 weeks (after the completion of the upgrade to the new Google Forms) and will take several months to complete.
Release track:
Rapid release, with Scheduled release coming in two weeks
