Hi, thank you for sharing this. Alright, we understand your point. Here’s the explanation for why this issue is occurring. Actually, it works with the old version.
If you use the Classic editor and classic widget, it works because it’s old, and there haven’t been any further developments in this plugin for 5 years. With WordPress evolving, many changes have occurred, leading to such issues. We’ve confirmed that it’s a valid bug. Currently, we’re addressing this plugin. We’ve recently initiated a complete redevelopment of this plugin to enhance user experience and compatibility.
A GitHub ticket has been raised in our repository regarding this concern, and it will be addressed in the upcoming update.
