In-play coupons on mobile?

I'm using the Blackberry mobile app for the first time.

Got the dreaded error 27 to start with so had to update my TCP/IP settings.  T-Mobile don't appear to be charging me any extra since changing the settings so that's a relief.

Anyhow, I notice that while the main site has coupons on today's in-play tennis matches, the mobile app has the link for coupons but returns "No events were found (16)" when I click on it.

Is it the case that the coupons aren't usually available on the mobile app?

I also tried Betfair Lite and I notice it doesn't even have a link for tennis coupons so I suspect the mobile app and the lite version are accessing the same underlying data.
