Probably the first weekend when VAR was used to iverturn decisions, and plenty got overturned. It looks like the powers that be decided to give it a go re-reffing the decisions. I think a few were incorrect (James’ penalty and the Arsenal disallowed goal, also the rugby tackle in the Arsenal match on Zaha, and teh Norwich goalkeeper coming way off his line for both penalties), but at least they are now happy to overturn decisions. They got a few correct too (Cantwell handball and Zaha penalty for example).
No idea why the ref doesn’t check the monitor though, small steps I guess.
