Is there a problem in IOS7 adding additional address to an email account
I have two email accounts set up on my iPad and iPhone one of these is an IMAP account. Under IOS 6 it was possible to add additional email addresses so that they became available in the "From' when sending a mail. Under IOS 7 this was made more obvious but I am having problems making it work.
If I go ino Settings/Mail, Contacts.../the account/ and select the account screen, under Email there is a Disclosure Indicator and when I follow that I see the list of addresses I had added under IOS 6 with an option to "Add Another Email...". If I select that I can insert an additional address at the bottom but there does not appear to be a way to save it e.g. no Done to tap.
Initially I thought this was an iPad only problem because I was able to set up a test address on my iPhone but having deleted this test address I now get the same behaviour on it as well.
Has anyone else come across this and if so did you find a solution?
iMac, Mac OS X (10.7.2), iPhone 4S and iPad
