Limitation in multilingual environment ?

I’m trying to use your plugin in a multilingual environment with Polylang. It runs well but I noticed that the checkout popup isn’t always displayed in the right language.
When the plugin setting “Stripe checkout language” is set to “Autodetect” the checkout popup seems to be always displayed in the so called Polylang “default language” as we expect it to be displayed in the “current language”, ie the one selected by the user for instance using a language switch.
When the plugin setting “Stripe checkout language” is set to a particular language instead, only the messages in the placeholders “Cardnumber”, “MM/YY” and “CVC” are translated accordingly and all other field names and messages in the popup are still translated in the Polylang default language.

As a consequence we sometimes get a mix of several languages on the screen and therefore an inconsistent user experience.

Is there any plan to improve the current situation or any way to bypass the current limitation?
More generally can we expect the plugin to be fully usable in a multilingual environment with polylang, WPML or any similar plugin ?

Thanks in advance.
