for Pro version support please use vendor’s support channel.
WordPress forums are for free plugins support only.
Hello @leyako
Thank you for your question.
It doesn’t have fully automatic compatibility with WPML yet but we will add it in the next versions.
Please ask your PRO version related questions here.
Indeed, the free version is the core version of the plugin, while the pro version uses the same core code without adding unnecessary elements. The free version is required for the pro.
The PRO version utilizes core version files and codes whenever possible, avoiding additional files or code.
I hope it helps.
Best regards
