Rich text in email signatures
Is there any way to have Rich Text (e.g. colours) in email signatures on iOS 11? In previous versions of iOS, I used to send myself the email signature, copy it, and paste it into the Signature setting in Settings > Mail. I then used to shake my iPhone and tap Undo Change Attributes; however, when I shake my iPhone now, the only option is to Undo Paste. I have also tried this on my iPad but it doesn’t work either.
