I ended up downgrading from Premium back to Business subscription because of this issue, OCM being the main reason I decided to upgrade.
After importing my contacts from CSV into OCM, it told me there were problems with 6 cards, but didn't tell me which 6 so that was useless as how will I find out which ones I need to re-import?
Then when I tried to delete the full contacts I realised there is no bulk delete on the portal (a default feature with any other online contacts management system and also Google Contacts!).
I then thought maybe I need to do it through Outlook, only to realise that Outlook 2016 for Mac doesn't support this feature either.
Not only you can't delete contacts in bulk, but you can't do anything with your contacts once they are there. No export option and no bulk select to assign categories, etc.
I think OCM is a premature product that should've stayed under the development bonnet for a little longer until it has enough features that makes it a potential competitors to what's out there.
