Upgraded to 5.58.1 this week and now AWS extension causing errors which slow down mail processing and lead to civimail mailings not going out. Each address leaves an error in the log from /civicrm/admin/job?action=view&id=1&reset=1:
Undefined index: job_id in Civi\Aws\Subscriber\Mailing->addTrackingDataHeaders() (line 153 of .........sites/all/civiextensions/aws/Civi/Aws/Subscriber/Mailing.php).
May be related to Drush errors I get:
Error: Array and string offset access syntax with curly braces is no longer supported in /sites/default/files/civicrm/ext/aws/aws.civix.php, line 246
