Outlook signatures

Hello

Please i need your help on this issue.

It no longer seems to be the client version or version of Outlook.

Please see below the Outlook New which is set up on a different device signed in with an account under the same tenancy with the same issue not being able to have multiple signatures.

 (This is now the same Version and Client Version of Outlook New on Windows 11/Outlook Web Access that many other clients and even myself and Stephan, who do have the option for multiple signatures.)
