Can't sign in without using Google chrome

Can't sign in without using Google chrome

I've only been using Zoho for a couple of weeks. As of a week ago, I'm unable to sign in using the app on my phone through Zoho. When I launch the app, 2 sign in buttons are displayed. One just says sign in, the other says sign in with Google. No matter which button I use, they both take me to a welcome to Chrome page with another button that says I need to accept terms of service. I have never used chrome or any of Googles apps, nor do I intend to. How can I get rid of this and be able to sign in to Zoho without using Google. Thanks in advance.
