Hello, everyone! (^_^)
Recently, in my gaming group, there was a bit of an argument about the effect of a dispel magic spell on an ethereal creature.
The creature we were fighting had cast etherealness (PHB, p228) on itself, preventing the PCs, who were on the Material Plane, from directly attacking it. Our arcane spellcaster wanted to cast an area dispel, hoping to end the etherealness spell and bring the creature back to the Material Plane. But our DM ruled that only a targeted dispel would work. He based this decision on his interpretation of the following part of the ehtereal jaunt spell, on which etheralnes is based:
He argued that an area dispel does not target the creature directly. Obviously, we pointed out the rest of the text, which says that abjuration effects extend onto the Ethereal Plane. We argued that the area targeted by the area dispel would be the same on both planes, but he refused to accept our argument. Since he was the DM, we had to abide by his decision.
My question is: is there any official ruling on this matter? Was it ever covered by the Sage Advice column?
I tried to find more details on this situation, but the passages I found pretty much just say the same as above:
To me, and my fellow players (and most people on this forum, from what I could find), it seems reasonably clear that an area dispel CAN affect ethereal creatures, provided they are inside the area of effect. But I'd like to have an official ruling, to try (again) to convince our DM.
Thanks!

(PHB said:(...) Force effects (such as magic missile and wall of force) and abjurations affect an ethereal creature normally. Their effects extend onto the Ethereal Plane from the Material Plane, but not vice versa. (...) (empashis mine)

(DMG said:The only exceptions are spells and spell-like abilities that have the force descriptor, such as magic missile and wall of force, and abjuration spells that affect ethereal beings. Spellcasters on the Material Plane must have some way to detect foes on the Ethereal Plane before targeting them with force-based spells, of course. While it’s possible to hit ethereal enemies with a magic missile spell cast on the Material Plane, the reverse isn’t possible. No magical attacks cross from the Ethereal Plane to the Material Plane, including force attacks.
(DMG said:A force effect originating on the Material Plane extends onto the Ethereal Plane, so that a wall of force blocks an ethereal creature, and a magic missile can strike one (provided the spellcaster can see the ethereal target). Gaze effects and abjurations also extend from the Material Plane to the Ethereal Plane. None of these effects extend from the Ethereal Plane to the Material Plane.
