Why do my lists keep disappearing? – Mail 2 Group Review

When I first used this app, it worked well. I use it to send emails to our retired coworkers. I use it a handful of times each year. Twice I have tried to use it and my list disappeared. I rebuilt them (no small task for almost 200 people). So just now, I attempted to remove a name from the app list and all it said was ‘ifailed ‘. Now that whole list is gone. Also, this app is not recognizing changes that I have made to my address list.
