After upgrade to PHP 7.4, Yoast breaks on pages using Connections plugin

I would like to use both Yoast and Connections. They didn’t have any problem when I was on old PHP 7.0, but after upgrading to PHP 7.4, all of my pages showing contact cards from Connections break with a fatal error.
The error seems to be coming from Yoast. When I disable Yoast, the pages work again, but I hope I don’t have to get rid of it permanently.

Here is the error. Thank you in advance for any insights!

Fatal error: Uncaught Error: Call to undefined method WPSEO_Utils::get_title_separator() in /home/casedupage/public_html/wp-content/plugins/connections/includes/Integration/SEO/Yoast_SEO.php:329 Stack trace: #0 /home/casedupage/public_html/wp-includes/class-wp-hook.php(308): Connections_Directory\Integration\SEO\Yoast_SEO::transformTitle('Staff Directory...', Object(Yoast\WP\SEO\Presentations\Indexable_Post_Type_Presentation)) #1 /home/casedupage/public_html/wp-includes/plugin.php(205): WP_Hook->apply_filters('Staff Directory...', Array) #2 /home/casedupage/public_html/wp-content/plugins/wordpress-seo/src/presenters/title-presenter.php(76): apply_filters('wpseo_title', 'Staff Directory...', Object(Yoast\WP\SEO\Presentations\Indexable_Post_Type_Presentation)) #3 /home/casedupage/public_html/wp-includes/class-wp-hook.php(308): Yoast\WP\SEO\Presenters\Title_Presenter->get_title('') #4 /home/casedupage/public_html/wp-includes/plugin.php(205): WP_Hook->apply_filters('', Array) #5 /home/casedupage/public_html/wp-includes/genera in /home/casedupage/public_html/wp-content/plugins/connections/includes/Integration/SEO/Yoast_SEO.php on line 329
