Do you have any other integration behavior configured (e.g. CBSubs Fields) that also is not working?
As far as I see, I didn't notice anything else unworking...
I tried to push users to share by themselves as possible, but the User Factor is un predictible or some couples have communication troubles - a few couples cannot apply basic recommandations and don't share properly their account, specially elder ones, that's why I have to create link by myself sometimes.
It occurs rarely so I will manage joomla user group umgrade handly.
Best regards
Antoine
