I'm having the same problem as Derpitar. It's happened more than once now- the connection is lost and when I refresh I'm given my opponent's point of view and switching options, though I can still use moves normally. The first time this happened I was able to switch to Pokemon that had already fainted, which was problematic, this more recent time I only had two options, both of which were grayed out, and I was forced to resign.
