My signature does not get picked while drafting a new mail on M4 Macbook Air using Sequoia

I recently got the new MacBook Air !

On up the same a very peculiar problem is arising:-

1. My personal Gmail account being set, when drafting a new mail it picks my signature.
2. My Company Account despite the same being hosted on Gmail is unable to pick my signature.

I would like to add that I was already using 2015 MacBook Air which had been working just fine. An had no such issue.
