Ok so i just bought an IPhone 5S and updated it to IOS 8 and i have been typing my friend who also has an Iphone but she has an Iphone 4S with IOS 6. when i type her a message the typing bubble doesn't show up on her end anymore, but when she types me a message it shows up on my end. I texted other people who have IPhones and they all can see when i'm typing. Before i bought my phone i had an IPhone 4 and it was working fine. Is it because she has IOS 6 and i'm using IOS 8 or what's the problem? Do you think she has to delete me as a contact then re add me?
