Hi there!
Those warnings can be ignored, this plugin should work just fine with the most recent versions of WordPress and WooCommerce. ??
What happens is this: each time a plugin like this one is released, it includes a line in the code that indicates the latest version of WordPress it was tested with. So for example, if WordPress 5.5.0 was the latest version when our devs last updated this plugin, then they will change that “Tested up to” line to indicate it’s been tested up to WordPress 5.5.0.
But then imagine that, the next day, WordPress version 5.6.0 comes out. Now, WordPress might warn you about this plugin, saying that it’s only been tested up to 5.5.0. That’s technically true, but not really something to worry about. It just means our devs have not updated the special line in the plugin yet, since a new version of Admin has yet to be released.
Does that make sense? Let me know if not. ??
