The EU never negotiated in good faith. Their goal is to punish Britain and discourage other nations from ever considering leaving their fiefdom. Wolf Street ran a two-part series about the progress.

"Brexit began in earnest…on January 1, with the entry into force of the EU-UK Trade and Cooperation Agreement. It is – at least to my mind – the first ever trade agreement that actively seeks to slow down the flow of trade between the two signatory parties. (Emphasis mine)

And the costs are mounting for companies on both sides of the English Channel, particularly the British one, and the benefits remain largely elusive. This is no great surprise; Brexit is a process, not an event, and it will take time for most of the benefits of separation from the EU to feed through."
