since the update to the 4.3 firmware, i'm not getting push notifications for facebook, skype etc. k9 mail and sms apps work just fine. i've added my accounts properly (google facebook etc.). tried disabling timescape and the sony social crap but that didn't help. i have no such problems on aftermarket roms (omni, cm).
i also downloaded push notification tester, and i can confirm that nothing happens after step 3 (trigger notification).
am i the alone with this? if not, is there a fix?
