EDIT: Graham asked me to post this to the public iOS forum to see if anyone else has run into this issue.
I was hoping to show this new feature in my webinar later today, but I can't seem to get the devotional default changed. It's showing one of the Butler titles (which I've actually never used, but this is a fresh install). I've tried moving a different devotional to the top in Tools: Devotionals assuming that would change it, but it doesn't. Also notice in the screenshot below that the devotional content in Butler isn't displaying correctly anyway.
I'm hoping someone will see this and provide a quick solution I'm overlooking in the next couple of hours before my webinar.
