To me a big issue here as well is the on field referees appear terrified to go against the VAR team. So they get called over to look at an incident and then bottle it and just go with whatever VAR has said.
Firslty fuck knows what the VAR team were thinking calling it over for a review anyway, then secondly the ref should have the fortitude to stand by his original decision instead of falling like a deck of cards.
This morning I put a recording of last seasons City v Leipzig on. Our first goal, penalty for handball, didn't touch the defenders arm but the ref was too weak to challenge Var. Its a shit show.
