E-Mail not been send

Hi there,

We got the PublishPress Notification system set up to notify our authors about new posts.
Unfortunately the system does not work since 13.02.2022…
I’ve already checked the troubleshooting-Page and checked the WP-Cron Manager but I don’t really know what to do to solve the problem ??

It sais “Failed – Error: The notification was set as “Scheduled” but the cron task is not found (asynchronous)”
I reinstalled the plugin already twice.

I got a debug-file, but no Log-file…
