@ebrett I’m so sorry to hear this has been your experience! I would love to help you get this properly migrated over in any way I can.
It is possible to re-run the migration at any time, which may resolve this for you. To do that, log into your wp-admin, and add this to the end of the URL:
?genesis-blocks-migrate=1
So the full URL would be this for your site:
https://YOURDOMAINNAMEHERE.com/wp-admin/?genesis-blocks-migrate=1
That will direct you to the migration page, and you can re-run the migration. Once complete, those blocks should be converted to Genesis Blocks.
If that doesn’t work, please reach out, as I would love to help you get this working.
Again, my apologies for the frustrations you’ve experienced!
