as per mattermost we have have an issue with the extension directory is pulling out older extension releases for CiviCore 6.0 instead of the release that matched for 5.83 e.g. https://civicrm.org/extdir/ver=6.0%7Ccms=Drupal%7Cstatus=%7Cready=/com.iatspayments.civicrm.xml v https://civicrm.org/extdir/ver=5.83%7Ccms=Drupal%7Cstatus=%7Cready=/com.iatspayments.civicrm.xml cc @totten
