I was composing a message with some autogenerated signature text. I entered a p.s. after the signature but it disappeared. I did it again and it was deleted a second time.
My rough guess is that nothing is allowed after the signature.
Is this a bug or standard practice.
Hope this helps.
When you say 'it disappeared' you make it sound like it just disappeared in front of your eyes without any input from yourself. However, this cannot be the case.
It will be replaced, for example, if you change the account and the new account has its own signature which is automatically inserted.
