@JeremyECrawford When does the Invisibility spell end: immediately before or immediately after you attack/cast a spell?

The invisibility spell is meant to end right after you make an attack or cast a spell. It doesn't predict what you're about to do! #DnD https://t.co/NPO8Yc6eE7

@JeremyECrawford Can a spell cast by a creature with the Invisibility spell active on it be counterspelled?
No because you can’t see it being cast. Unless, of course, you can see invisible creatures.
