Welcome to the Forum @Judes 
and thank you for reaching out!
Apologies for the trouble here. I can confirm we have recently made some updates to our email security protocols in order to strengthen account security. Please have a look at the steps shared by one of our community member in Recent email security update. How to fix “We couldn’t process your email” to update your gmail settings accordingly!
I hope this helps Judes but please let me know if you need further assistance!
