OnePlus proudly announced before launching the OnePlus 3 that they were finally doing away with invitations once and for all. The teething pains that necessitated that queuing system no longer exist. Or so OnePlus thought. It seems, however, that OnePlus still has a few lessons to learn in supply and demand. It has just apologized for and explained the delays that its UK customers are going through and offering discounts for their next purchase as compensation for the delay and stress it has caused.
