Is the turn of other people dragon's bugged?

Thursday is maintenance day (at 10:00 CET)! We are trying to keep it as short as possible.
  • Am i the only one finding it hard to turn of the dragons. When our guild does guild boss, can't even see the boss due to all the dragons. I tried to ask friend to open their dragon while i click every button in the interface to turn him off and it doesn't work. Will this be fix soon? It gets annoying for guardians who has to be in front.
