I found a workaround for this issue. We were using NSHealthShareUsageDescription as the key for the localized string in our plist, i.e. In our plist we had "NSHealthShareUsageDescription" => "NSHealthShareUsageDescription" And then in our localized strings we had "NSHealthShareUsageDescription" => "Some localized string" Swapping the key of the localized string over the full EN localized string has fixed the issue. I.e. our plist now has "NSHealthShareUsageDescription" => "Some localized string" And our localized strings has "Some localized string" => "Some localized string" (localized)
