My mantis app begins opening and then shuts down. I've had numerous bible studies that I have added to this app. Each time this issue occurs I must delete the app and redownload. I don't have a problem doing that I understand software has glitches. My main issue is with the backup. After I reinstall the app I restore from backup and there are no backups displayed (IT IS COMPLETELY BLANK). I backup this app at least once a day to save all of my bible studies. Why aren't my backups showing when I go to restore from back up? Please help I don't want to continue added bible studies knowing they will not backup. Thus wasting time that I can never get back. Thank you
