Anyway, I'm glad you were able to sort things out in the Play Store. It makes sense that both my Android phone and your Android tablet would have some similarities with the App Updates, as we both use Google Play to get apps.
I agree you are better off not doing that Update All thing. I have sometimes run into problems doing that, getting errors and the updates getting stuck downloading for what seems an eternity, with no final installation, and then having to stop them all and start over updating them one by one.
