Tears and disappointment flowed Monday after newly sworn-in President Donald Trump cut off a mobile app that allowed migrants to apply to enter the U.S. legally as asylum-seekers. All pending appointments made with the app have been canceled, too.

The CBP One app was set up under the Biden administration as a way to curb people crossing the southwest border illegally to request asylum. Once it went into effect, it was the only way for people to get an appointment to request asylum.

Monday afternoon, Customs and Border Protection posted on its website that the app was no longer available for that purpose and “existing appointments have been canceled.” Some 280,000 people were logging into the app daily to secure an appointment as of Jan. 7, according to Reuters.
