Mautic Hubspot Integration - updates not working

Your software
My Mautic version is: 2.16
My PHP version is: 7.2

Your problem
My problem is:

The hubspot integration with mautic doesn’t push the updates done to the contact after the intial transfer of the contacts.
For eg :- An update in phone number done in hubspot is not reflected in mautic and vice versa
The mails sent via hubspot are not in the mautic audit trail and vice versa

Commands used :-
mautic:integration:fetchleads -i Hubspot
mautic:integration:pushleadactivity -i Hubspot

Is there something that is missing in terms of process?
