Here's what's happening with mine: MM Web > iPhone : Push Instantly iPhone > MM Web : Push Instantly MM Web > Home Mac : Push Instantly Home Mac > MM Web : 15 minute interval or manual sync (as its supposed to be.) Here's where it's a bit different: MM Web > Work Mac : 15 minute interval or manual sync For some reason, MM Web is having trouble triggering my Work Mac to update instantly. So, it acts differently at work than my home network. I work at a University, so this leads me to believe that its a problem with my firewall or ports. Any ideas?
