I had the free version and the email to the worker was working great.  I used that to do integration with meeting app.   I upgraded to the paid version and now this is not working.  I re-entered the email settings, and I sent a test email which did not work.  So, this is very strange.  What could I check?  (I am using the paid version 0.9.7) Further, although the google calendar integration is sending meeting data to the calendar, it is not using existing calendar info to block appointment times.  This is critical as its the whole point of the calendar.  We need to prevent users from double booking.    Is this working as intended or is there a configuration issue? I just disabled the paid version and the email is working again.
