Hey toothsuiteio_dtg5697y ,
Thanks for reaching out to us 🙂
Since version 3.0 it's no longer required to install a separate premium version of Buttonizer.
You can keep the free version installed, connect your site, then go to the Buttonizer Settings and click
Sync with dashboard. It should now show you that the PRO is activated.
Let me know if this helps 🙂
