What happens if a controller instructs you fly at 3,500, you climb to and level off at 3,500, and then you cancel flight following? Are you required to continue maintaining that altitude? If so, for how long?I am loathe to derail the thread with something that's been covered a thousand times, but for the peanut gallery, no, if ATC gives you an instruction that you don't want to follow, canceling flight following doesn't get you out of it.
