We have updated all Drupal 9 sites to use the Claro theme for editing and other administrative tasks. Claro is the new default administrative theme for the Drupal project and includes significant design usability and accessibility improvements. There are very few functional changes with this theme. If a button or field was in one place on the old theme, it will be in the same place in Claro, but it should be easier to see, click, and use.
