Several members in our Stake are having trouble with members tools after the last update. The app keeps freezing. You can't go to the menu. I have uninstalled many times and reinstalled. But still keep freezing after a few minutes.
It would probably be best if the affected members report it though the app. The report will send some information about the device to help the developers spot a pattern.
