Fans have been confused by the use of two different VAR systems for this week's FA Cup fifth round ties.
Premier League heavyweights Liverpool, Manchester United, Newcastle, Manchester City and Chelsea are all taking part in the fifth round.
Non-league Maidstone had their fairytale run ended by Championship side Coventry on Monday night after Mark Robin's men booked their place in the quarter-finals with a 5-0 win.
Fellow Championship sides Blackburn Rovers and Leicester City both faced Premier League opposition.
But VAR will only be in use at Premier League grounds for FA Cup fifth round ties due to licencing rules.
The prestigious competition has used VAR since 2018, when it was used in a trial format.
However, it has only been used at Premier League grounds as the FA has never applied to the International Football Association Board (Ifab) for full use across all fixtures.
It would be complicated and expensive to install VAR at some EFL and non-league league grounds, meaning it wouldn't be a worthy investment for a one off tie.
With just Premier League grounds allowed to use VAR, Bournemouth, Luton, Nottingham Forest, Chelsea, Wolves and Liverpool will all have it in use for their FA Cup fifth round ties.
But the two games hosted by Championship sides - Coventry and Blackburn - will not have the technology available.
The FA has been criticised for creating an imbalance in sporting standards in the competition.
