Worth buying?

I wanted to write to the developer, as I’ve been testing out many Recaptcha plugins, and very few seem to work with targeting logins that appear in popups, but yours does. So while I’m happy to find that, I’m quite concerned this plugin hasn’t been updated in over 8 months and is not compatible with the latest WordPress. It seems unfortunate, as I see even large developers like Crocoblock reference your plugin, that’s how I found it, but the compatibility makes it risky to install. I just wanted to see if there was any response to this or planned upgrades to the plugin, thank you.
