LDS Tools AP on Iphone not working

I have used the LDS Tools/Directory on my Iphone ap almost every day until recently when it stopped working. It will allow me access to the ward directory names, but won't allow access to the telephone numbers and addresses. Has anyone else had this happen recently? What can I do to correct the problem?

In other threads, some users ended up uninstalling and reinstalling the app.

In the last week or so the app was crashing for me when I tried to click on a name in the directory to get more details about that person. Same thing was happening on my friend's iPod Touch. All we did (which solved the problem for both of us) was update/refresh the data rather than re-install the whole app.
