OP: PLAY-INS DAY 2

The definition of an 'obvious play' is: "Plays that are clearly visible to most of the participants in the game, including referees, coaches, players and spectators. Referees must be correct in this type of situations 100% of the time with no room for error.

However, for several reasons, we have had some OP in the last day of competition, shown here. Please analyze carefully the resons for not having the correct decision in these plays.
