InMobi: Ads showing on iPhone but never on IPad

My issue is very simple to describe:
Ads showing on iPhone but never on IPad on same app.

The app runs OK in the iPhone getting test ads from inMobi.
When the app is run on iPad2 we always get “InMobi:Ad request failed.Server returned a no-fill.”

A email sent to ansca@inmobi.com in Aug/16 have no answer so far.

Is this a common issue?

We’re not seeing this in our testing. Does this happen for you with the InMobi sample project? [import]uid: 6787 topic_id: 14238 reply_id: 53812[/import]

Same here. Shows fine on iPhone 3GS and iPod Touch 4G but not on iPad. Makes no sense. Can we have return values somehow so that we can debug this? Tried several Corona versions.
