It's happened to me, too.

I never thought this would happen. I saw it happen to others, and always thought to myself, "How can they let this happen? What are they doing wrong here?" Well, I can no longer ride high on my mighty horse.

Why? I've filled up a 64GB iPhone.

Yes, I'm working on clearing out Overcast. I have a habit of stopping episodes with ~1 minute left causing them to not delete until I reach the "keep n episodes" limit. But I think this means my iPhone 6S+ (Yes, I'm going BIG this fall!) will be 128GB.
