JustWatch: Cannot set primary country

Short description of the issue

I’m trying to set my primary country for the JustWatch integration, but I can’t find where to do it.

Detailed description

I looked for the setting in my account settings and in the Where to Watch section on a movie’s page.

After accepting the cookie prompt, the popup only shows the available streaming providers and countries. It never asks me to select or set a primary country.

My understanding is that setting my own primary country should be available for free, while checking streaming availability in other countries from the popup is a VIP feature. If that’s correct, I would still expect to be able to choose my primary country, but I can’t find the option anywhere.

Am I missing something, or is this a bug?

Thanks in advance!
