Unable to login to iPhone Zoho Mail App - "Looks like you recently changed your Zoho Password"

Unable to login to iPhone Zoho Mail App - "Looks like you recently changed your Zoho Password"

The message is "Looks like you recently changed your Zoho Password..."

Indeed, I did.

When I enter the new one (which logs me in correctly in a browser), I get the message "Oops! Something went wrong."

I've disabled MFA.
Deleted and reinstall the app.
Logged out of all zoho apps on the phone.

How do I fix this?
