There is no 14-day discovery grace period to complete. You do not lose your account because you have not filled every optional profile field in two weeks.
Review your chart, discovery location and profile visibility instead. Follow any account verification requirement shown in the app. Recommendations depend on eligible people within both members' settings, so they can still be empty.
Phone verification is currently unavailable. Do not wait for an SMS code to complete a step that the app does not offer. If a required step stays stuck, contact support with the page and error message.
