Hi Eric,
I do know that as part of implementing the new calendars they did make a change to how they send out in subscriptions. If you feel this would be a beneficial feature in Quick Base, I would encourage you to submit feedback regarding this via our Feedback Platform - UserVoice - Which can most easily be accessed from the My Apps page in Quick Base by clicking on the orange Feedback tab or at
http://quickbase.uservoice.com . This forum is used by our development team to explore customer suggestions for enhancements / changes to the platform. Many of the items that have been suggested by customers have already been incorporated into Quick Base and I would encourage you to participate as well. This helps us to gauge if there is interest among our customers to bring this feature back or build our a new, similar feature. Thank you very much for your time today.
