Sharepoint designer 2013 workflow content approval doesn't send email for some reason

I have a list and i have set it to use the require content approval. I created a workflow SP 2013 to send an email when

If Approval Status = "Pending"
 - Send Email 

When i run the workflow manually or when an item is created it doesn't send an email. But when i use SP 2010 designer workflow it works. Why is SP 2013 designer workflow isn't sending emails. Am i missing something with the content approval with SP 2013 designer?

See screenshot of workflow here :- https://ibb.co/z5MSGfD

It seems the OTB content approval doesn't work with sharepoint 2013 workflow.

Anything after the 

If Approval Status = "#Pending" or #Approved

doesn't trigger at all.
Can anyone from MSFT or here please confirm that too?

Thanks in Advance
