On the mobile app, when viewing any token within the Price tab, the fiat currency shown defaults to US dollars instead of respecting the user’s selected currency preference from their account settings.

All mobile app users who have changed their default currency to something other than USD.

There is no direct workaround within the Price tab. You can upvote this forum post to indicate you are experiencing this behavior. The post status will be changed to Complete once a fix is rolled out to all users. Up-voters will be notified of the status change.
