Thanks for your feedback. This update provides additional control and monitoring of assets. In most cases the update is transparent, however for users who get entitlements from several business orgs, this provides the necessary separation of assets.
On inviting/adding a user they do receive an email invitation. However, it is *no longer* necessary to track down the email. When users sign in, if there are any pending invitations, they'll be prompted to join the team and may be prompted to move their assets. If users have entitlements coming from several businesses, we can't offer the choice of migrating assets and leave them behind in the Personal profile.
There shouldn't be any missing data; it's most likely in the Personal profile.
If you're facing specific issues, please let us know and we'll try and help.
