Still no "Send to Group" functionality!!! We have to go in via the desktop web interface and set up segments for each combination of groups we want to send to in order to use the MC Snap templates for our very granular customer list. Not being able to checkbox various combinations of recipients is making MailChimp suboptimal for our business when it would otherwise be great.
I really look forward to you adding the feature back so I can leave a 5 star review for an otherwise great app and move on with my life.
