For the last several days, I'm getting no push notifications on my Droid 4. Gmail doesn't sync unless I go in and refresh, and I have a few other apps I use push for (Facebook, etc.) and I'm not receiving those, either. Once every day or two, I'll receive a huge slew of all my notifications since the last time they came through, then back to nothing.
I checked all of my settings, even though I certainly didn't change anything, and everything seems to be set up to properly sync and push. Data connections otherwise work fine (well, as well as they did before this issue came up, but that's another topic).
Phone is just over a year old, running ICS version 4.0.4.
Anyone else experienced this? Any suggestions?
