After our chat, I spoke with one of our developers and there is a suggested workaround, however keep in mind this will add taxonomy translation access to anyone with the editor role. You can place the following code in functions.php and run this one time to generate it:
Thanks Lauren, it´works! Thanks to you and all the team for the fast workaround <3
I agree that granting taxonomy translation access to anyone with the EDITOR role is not ideal. But in our case, having to give ADMIN access to all the translators would be much worse!
We hope that Avada and Wpml find a way of making the Avada sliders translation work as the rest of the elements.
