Better International Partner Tracking
Partner Tracking once an item has been handed to international partners is awful. The worse one being PostNL - tracking never works on their website, and their reason is that it's due to the address not being digitally sent to them via Royal Mail.
What this means for NL parcels, is that tracking is non-existent once RM has handed it to PostNL, causing NL customers to constantly email to ask for an update. We need better tracking between RM and their partners.
