Voting starts in March for the Drupal Association Board election.
When we initially installed and setup the module we were able to upload a default thumbnail in the field_video settings. We have the module pulling thumbnails, the user can choose either one of those or the default thumbnail.
At some point we decided to change the default thumbnail, unfortunately once removed we can no longer upload or otherwise add a default thumbnail back to the field. This is enormously inconvenient, why can't you adjust default thumbnail after data is in the field?
