You appear very optimistic here. 

There are known issues in the Acrobat signature validation code that haven't been fixed for years.

But maybe you're lucky 😉

Dear Souvik

This seems very unprofessional.

That this case is being pending since more than 6 Months.

This matter have to be escalate in Adobe Team with your seniors, also I have asked same in earlier thread that is your team really aggressively working on this issue or not.

Thanks & Regards
