Installed on recent released HTC and alway errors on backup attempt

Easy to install and not much to setup.  Nice interface but doesn’t backup.  Always fails at around 40Mb or so.  How do you troubleshoot this?  Seems this is one of the better apps for backups on Google Play but it does nothing for me.

Anyone able to help?

No one…after all this time?

Plus…where is the option to stop a backup in progress. Trying to kill the app doesn’t work.  Have to restart phone which makes no sense.

Going …going gone? Delete?
