Hi,
I have a Prime Amazon account, which has always had the 'buy now' box on it, on my I-pad and I-phone app. Until last night, when I discovered it has gone from my iPad 
I still have it on the phone, however. I have not changed anything, as far as I know, so just wondered if anyone else has had this happen?
I have emailed Amazon but no idea if or how soon they will respond.
TIA.
