I was able to reproduce it on an out-of-the-box install with these steps:

1. Create a free development WordPress site on https://pantheon.io/register which defaults to PHP 8.1
2. Add define('WP_DEBUG', true); in /wp-config-pantheon.php
3. Install the Watu plugin and activate it.
4. The warnings appear on the WP admin dashboard and plugin listing page.

I noticed that this was marked as resolved, however after upgrading to version 3.4.0.1 of the plugin I’m still seeing these warnings.
