Error in logs get_instance

Hi all,

I am using mailpoet and contactform 7, which are working fine.
But I do notice errors in the logs concerning the usage of an deprecated function
[09-Jan-2019 07:07:56 UTC] PHP Notice: WPCF7_ShortcodeManager::get_instance is verouderd sinds Contact Form 7 versie 4.6; gebruik in plaats daarvan WPCF7_FormTagsManager::get_instance. in /www/wp-content/plugins/contact-form-7/includes/functions.php on line 374
This function is present within the file “add-on-contact-form-7-mailpoet\includes\class-mailpoet-cf7-submit-form.php” on line 49
Can this be improved by using the proper function please ?
E.g. WPCF7_ShortcodeManager –>WPCF7_FormTagsManager

Regards,
Peter
