I've tried about 12 different Facebook apps over 6 months, I've reinstalled them all, reset the phone, reset the firmwre via Nokia Care, still I've only had two notifications, for about half a day yesterday< before they started working again.
I don't think Windows Phones were designed with functionality in mind.
Same here mate.... I am totally upset with WP... People say we have to be patience, that iOS took 5 years to be what it is today and WP is just released but the lack of BASIC features and amateur issues are to be blamed!. Here goes the list I have noticed after 1 week using my Lumia 920:
1) Facebook integration is weak (from time to time it says it cant connect to the chat or cant refresh feed with no reason at all - wifi and lte working. Not to mention that I can't receive any message form a contact that is on mobile chat - e.g. iPhone FB messenger app).
2) There is not a single message app that works (tried WhatsApp which drains the battery and have notifications issues and Vibe that I could not receive a single notification for incoming messages);
3) Skype is S****! How could MS turn its backs on skype for WP? I just cant get it... All other OSes have fully functional Skype while in WP it screws up big time! I cant even add a contact. (have tried to invite people from web outlook.com, but people doesn't get notified of my invitation). So basically MS bought Skype for nothing...
4) I can't lock rotation;
5) XBOX Music doesn't have gapless playback which makes listen to live albuns a pain in the heck! (seriously MS?? I mean, this feature is present in iPod for years!!!);
6) No separate audio volume for phone call, headphone and interface;
7) The lack of supported format for video playback;
8) I'm not and audio file, but the stock headphones are awful. Completely useless!
9) Find my phone location thru the windowsphone.com turn out to be an impossible mission (it says it cant be located, that i should try again.... and again.. and again... And yes, i have enabled the location service in my Nokia 920).
10) Install apps thru the web just not happening...
11) Turns out that notifications and WP have a complicated relationship and could not coexist... We relay on notifications every single time nowadays and MS not seems to know it.
Really hope most of that annoyances get fixed on WP 8.1
