Running WP5.5.3
PHP 7.4

Tried deactivating and reactivating AND have tried removing and reinstalling…to no avail…

I am still having issues with the this plugin (across dozens of websites – all using different plugins and themes) ALL the errors are the SAME…

The PHP errors are as follows:

———————-
An error of type E_ERROR was caused in line 787 of the file /home/directory/public_html/wp-content/plugins/companion-auto-update/cau_functions.php. Error message: Uncaught Error: Call to undefined function wp_next_schedule() in /home/themename/public_html/wp-content/plugins/companion-auto-update/cau_functions.php:787
