Everytime the cron runs I now get this. I configured Oauth2 for just email IMAP all went fine and up updated and enable with not issues. I think this the last hurdle.

PHP Fatal error: Abstract function osTicket\Mail\MailBoxProtocolTrait::oauth2Auth() cannot be declared private in /var/www/clients/client0/web3/web/include/class.mail.php on line 238
