Why I cannot update some apps?

> do you set uo these apps by the same apple id?

A good catch! Indeed, I could install some apps from a different ID.

But there are NO prompts for ID at all. It just starts downloading and fails to complete.

Where the ID used to install a particular app can be seen?

No useful hint is given as to why download fails, just "cannot download now, try later".

But the failure always occurs at same place, so I know it is not random.

Thanks.

Go to itunes bottom of page Sign out then Sign back in

Why iTunes? This is a standalone iPad, it is not connected to any machine with iTunes.

Ok, I can install new apps, prompted for the store password, everything is well. Except of these <beep>ed two apps.

So, the store or iTunes theory is dismissed, right?

On Android tablet on the same wi-fi router, both apps installed just fine (Android versions of course).

Now I'd like to ask, where the apps are downloaded from: a central server at Apple, or server for each app is owned by its vendor?

If the latter, I'll try to follow up with the app vendors.

Update... All of sudden, the Dropbox app has updated successfully today (and couple of other large apps also updated just fine, on the same wi-fi router).

But still not Viber.

So ... now I doubt that this is a networking issue at all.
