Went to BlackBerry web site and clicked on link to App World. App world opened on my PlayBook no problem. Updated a few apps without hesitation. Closed Browser and App World on PlayBook. Then opened App World on PlayBook. Got error notice of not available..... Interesting why it would work when following link off website yet not in App World off PlayBook. Perhaps an issue with in App World app on PlayBook?
It's not working for me here either in the UK as of yesterday. I had changed my PayPal payment info yesterday and assumed that that was what had mucked it up, but it seems that perhaps it's a service issue instead?
