I've noticed lately that any app I download that has a live tile crashes when I try to run it. Any other app runs fine. I was curious that this might be a result of the 15 push app limit. So, I went thru all my apps that have live tiles, removed them from my start screen, and unchecked "live tile," "push notification" or whatever option they had. This did not fix the problem, even after a reboot. If i re-pin one of the old apps and enable live tile, they work just fine.
I'm wondering this is just a glitch with my phone, or whether wp7 doesn't have the ability to release the "hold" that an app has on one of the 15 available channels. Is anyone having this same experience?
