Translatepress compatibility

Hello,

I purchased the plugin and I see that it’s only compatible with Translatepress for logged-in users. It works fine.

However, it doesn’t work for guest users because they don’t have a wpuser profile, and therefore Translatepress hasn’t saved any metadata on their profile. How can I make it compatible with guest users as well, please?

Is it possible to update the plugin so that it also saves the language the user is using when visiting the website?

Sincerely,

Camille
