Hi @mikes41720 ,
We are facing a similar issue after the recent update. Please note that we are using your premium version.
I have done the troubleshooting the Health Check & Troubleshooting plugin.
Steps as bellow;
1. Enable the troubleshooting mode
2. Enable the Classic Editor Plugin
3. Enable the Yoast SEO Plugin
No issues in this step, everything works as usual
4. Enable the Yoast Yoast SEO Premium
Then the meta boxes disappears. I tried few times like above, every time without Premium version it is working fine. So there must be an issue with Premium version.
error report from console:
TypeError: (0 , _element.createInterpolateElement) is not a function
