Can't download my grey apps
I bought the new Iphone 6s plus , I backed up my old IPhone 5 and the I connect the new IPhone to computer to restore the back-up on the new IPhone. Some of the apps were transferred correctly and some of them did not . So, I went to the Itunes app to download them but I couldn't find them . Also, when I double click on them the waiting word appeared but not one of them is installed.
So, please advise me what to do ??
