Core functionality not working

Bought the app a year ago to get tasks and briefcase items on my iPhone. Tasks work well enough but briefcase items will not work. After no response to my emails I called Aderium and they admitted that Zimbra briefcase docs do not work but an update was about to come out to fix this. No update ever came out so the app is virtually useless for me. iPhone already has a tasks area that syncs with my server. Very disappointed in the lies.

No decent Zimbra app about Aderium Companion for Zimbra, v1.8.2
