Unable to Update Pending Page When it Submit for Approval Work Flow

[Fatimah_33]

I have created a workflow that sends approval for creating a page into a site.  After the approver got the message to approve the page, he can't update/edit the page. He has to submit another approval for updating/editing that page(that's not correct). The first creation of the page will lose his approving flow. 

My requirements as follow:

1- The requester will create a page then a message send to the approver 

2- The approval will be able to edit the page and then approve it. 

3- The requester will receive a message for approving his page with new editing by the approver.
