I hope there is no other thread with this problem. I couldn't find anything.
So the problem is i don't get all updates to the application manager and can't update some apps via store...

i had this problem now with MeeCast and Fahrplan. There was no notification in app manager but store showed me that there is an update... when i try to update via store is sais "can't install application allready installed"

this is not for all apps so i have no idea whats the problem
