One more thing -- I spoke too soon when I said the Quick-Add button was a (partial) solution to the issue I raised above. It IS indeed a solution for my iPad, and it works just as you said. Unfortunately, that's NOT the case for my iPhone.
when I press on the Quick-Add button on my iPhone 6s, from either Set List view or Smart List view, my phone freezes entirely, and I have to close Band Helper and re-open it. That's unfortunate because most of my use of Band Helper when I'm at a music session is from my phone. So, I won't be able to use the Quick-Add button as a search workaround (or for anything else....) until this is fixed. I already submitted a help ticket -- I just thought I'd also post here, in case anyone else is experiencing similar problems.
If you have any ideas about how to fix this, or if you've seen it before, I'd love to know. Thanks!
