My Lumia 920 got replaced on warranty some time ago because of a glitchy touch screen. After having the new one immediately sent in for repair too, I got it back and have been using it a couple of weeks now. However I got this problem with the app updates not showing, never had that issue on the old one. I have tried re-pinning the live tile, soft reset and most of the tricks mentioned but nothing helps.
However someone mentioned logging in to windowsphone.com and delete any extra phones...
Now I have always had 2 phones (my original 920 and my 800 work phone) tied to my Microsoft account, this hasn't caused any problems. However since I started using the replacement 920, there is now 2 920s in the list for a total of 3 phones. I can determine which one is the original, now scrapped 920 (shows a location with timestamp a couple months old) and my current 920 (shows my current location and current time). However when I try to erase the original 920 from the list, it asks me to enter my phone number, then after trying to erase it I get a message saying it did not succeed. This makes sense because the original 920 has no SIM, is not turned on and is in fact scrapped, and the SIM with the phone number is now in my replacement 920.
Since somehow this is related to app updates not showing, I suspect that this might be the problem in my case. Now my question is, how can I unlink the old scrapped 920 from my MS account, leaving only the current one?
