In the update Tab i have all my app show an error because Mitch can't found update (and all my app is already updated) 

If you press on an item in the update list, does it give you an error message?

No juste the popup to send a mail

Ok so i tested something (i have an SD card on my phone as an extended storage my apps install to it automaticaly) i put the app on my phone and now it didn't show up any more and another one of my app got an update and i can update it without probleme.

So it's not a huge issue :)

1 app that is on my phone show in the update Tab to... so it's not a SD card probleme... :/
