I can understand the bug. I will be updating the plugin to fix this within a few days.
WordPress didn’t have any hook to integrate a code just after body opening tag. So, I had integrated it with ‘wp_head’ hook.
Now they seem to have introduced a new hook for that and not all themes have adopted that hook yet. However, I will be finding some solution to this in any way so it doesn’t affect SEO.
I appreciate that you informed about the issue.
