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 🙂
