I configured Gmail to send emails from different sender addresses. For one of these addresses, I configured a signature. This worked quite well. When creating a new email I can choose the sender address and, automatically, the signature appears in the text field.
The problem: This does not work any longer. I have no idea why. I tried this on different computers, browsers and Gmail-accounts. They all behave the same.
Answers to questions in the comments
- There is no special formatting in the signature. In Gmail Settings it is configured as 'only text', not as 'rich text formatted'.
- There is no "show trimmed content" (three dots) button below the message.
