This is different from the smart cover compatible warnings. I just recevied an email from the Amazon seller that I bought the rooCase from. They are stating the sleep/wake function is not working and they will send me a replacement. I have not tested this yet since I am still waiting for my mini (hurry up FedEx ).
Thank you for your recent purchase of the rooCASE Ultra-Slim Vegan Leather Folio Case for Apple iPad Mini 7.9-Inch Tablet - Thinnest Folio Case - 17mm!
Unfortunately, it has come to our attention today that although the case you've purchased fits the iPad Mini correctly, the Sleep/Wake feature is not supported by this case. I apologize for the inconvenience! The manufacturer is already working to resolve the Sleep/Wake feature and you will receive the corrected replacement case at no additional charge to you within the next 10-14 days. The corrected replacement case will be sent out to you without any further action on your part. You do not need to send the original case back to us it is yours to keep free of charge so that your new iPad Mini will not go unprotected while the corrected case is on its way to you.
