I've had this problem before, and last time I cleared Gmail cache and it worked. 2 days ago it stopped working again, I cleared Gmail cache, and it's no help. Now I have to manually refresh to check my Gmail, which is really pathetic cause I'd think push email (and Gmail out of all email services on a google-powered phone) should be the core functionality of the Droid. And yet this feature is so buggy it makes windows 98 look stable. What's so hard getting push email right? Why can BB do it, but not Google? What's the technical difficulty here? I'm starting to feel like this Droid is good as a gagdet, a toy. Not nearly ready for primetime. Ages behind Blackberry. NEVER EVER had a problem with push email on Blackberry. Wtf?! (sorry for the rant, but this push email not working + slow UI on the Droid is really really frustrating and makes me want to return it and go back to my reliable blackberry.).
