That works--if I scroll to the sixth item, the seventh is brought into view and I can then click on it. But that makes the task dependent on the number and order of the lists; the list I'm scrolling to must be in that sixth position, and I was trying to avoid that. And if I were to add an eighth list, it probably wouldn't show after that scroll, and then would fail.
I switched to using a swipe gesture to scroll to the bottom. As it happens, that puts all seven playlists on the screen and I can pick from there. That makes it order-independent. I think I could even fit an eighth list. If I ever create a ninth, this will probably fail, but I'll deal with that if it ever happens.
But I'm still curious: Is it true that Scroll Forward should only work if the target item is visible? I ask because I was able to scroll to the fifth and sixth playlists, which were not visible. Not sure what the real limitation is.
Thanks!
