Changed MX records and still receiving emails in OLD host webmail, and NOT IN ZOHO

Changed MX records and still receiving emails in OLD host webmail, and NOT IN ZOHO

Hi, i had my OLD hosting for Website and Email at Hostgator.

Ive already changed the MX records at the Registrar (domainmonster) for the ZOHO and theyre correctly saved. I did this 24 hours ago.

I changed also the A records because i created a new website at Weebly and the website is correctly working.

** I still receive the EMAILS at the Hostgator webmail of myaccount@mydomain.com there
** I do NOT receive the EMAILS at the ZOHO mail when i open the APP or the Webmail
** I DO YES receive the EMAILS sent from the ZOHO webmail and app to    myaccount@mydomain.com at ZOHO app and WEBMAIL
** I DO NOT receive the EMAILS sent from the ZOHO webmail and app to    myaccount@mydomain.com at HOSTGATOR  webmail  of myaccount@mydomain.com


HELP please.
Best regards
