Hi there - I am not receiving zoho emails. On my app there is nothing to say why, and on full website nothing shows when I'm in the 'newer version'.  But when I switch to the 'older version' the above error message shows.

Can anyone help please?  I have looked at my settings but can't see how to change the port.  Zoho help desk not responding to my emails or my phone messages which isn't great service.

Thanks

Mandy
