AD B2C Custom policy

Good evening,

We've developed a custom login and sign-up policy on AD B2C. The login process had three pages: 1. Phone number entry, 2. Country code and phone number(Phone number is added automatically from step 1) entry, and 3. OTP verification leading to token generation. We want to optimize this flow. Now, we aim to eliminate the first page and directly present page 2 (Country code and phone number). Although we've updated the journey and technical profile accordingly, the HTML rendering isn't functioning correctly. Is there something we overlooked?

Is there any other way to do it?
