Can't Enable IMAP (no save button) or set up Android Access

I have gone through the step by step multiple times and keep getting an error message that just sends me back to the step by step info.  I believe the problem might be with enabling IMAP on Zoho as there's no save button.  A pop up says changes were made successfully, but it doesn't stay that way.  I have POP3 enabled and tried setting up via that option, but still get either links to instructions or that the server can't be reached.  How do I fix this?!  Thanks.
