LDS Tools Feedback - Lists

I am using the lists feature and when I had too many people from my ward into a list I create and then hit the map icon at the bottom right to show all those people on the map, the app quits. I am the elders quorum pres. in my ward and if I could get this to work it would really help me and my calling. I have the latest version of iOS and an iPhone 5 from two years ago. Thanks for taking a look at this.

[Moderator note: This thread was split from the LDS Tools Feedback thread in the LDS Tools forum because they discuss different topics. Additionally, LDS Tools for each operating system has its own forum and the topic of this thread is specific to iOS platforms.]

How many people do you have in the list? It's possible there's a limit to how many people LDS Tools can mark on the map at a time.
