Passwordless bypass captcha?

I had setup passwordless flow on mobile, I’m enabled Bot detection risky too.
When Auth0 detect some risky account, Auth0 show captcha immidiately to challenge user on Universal Login, but in passwordless, it’s just block account (cannot verify OTP) and I dont know how to by pass this challenge.
Many users complain that they cannot login though fill correct otp code (they are blocked )
So how can I by pass this captcha or some method to resolve this case ?
