Adding 2nd email account in Zoho Mail App (iOS)

Adding 2nd email account in Zoho Mail App (iOS)

I have two email addresses with Zoho, from different domains
e.g. emal@domain1.com and email2@domain2.com

When I log in to the app with the first email address, whic is my admin address for all my emails, then I click the Settings icon and click the "Add Account" text.
Every time I do this, the screen changes to "Fetching your account", and then brings me right back where I was.
In other words, it never asks me or allows me to add the second email address.

Is there something I am doing wrong?

Thanks

Garrett
