2 weeks ago we successfully used the ROAM app to clear into Culebra. The crew included US citizens and US permanent resident.

A few observations:

- The app repeatedly closed when run on a near 5-year old Samsung Galaxy S5 phone (though it had successfully run in November). The phone's memory cache was cleared, but this didn't help. May just be too slow a processor.

- Upon loading the app to a Samsung S8 phone, we got the app to run but got a repeated error message that we had not given the app permission to view our location although we set this permission to ALLOW when we loaded the app. We finally got it to work by resetting the permission to Deny, and then when we got the error message the app took us to the settings page where we reset the permission to ALLOW.

- Once we were able to submit our clearance request, it sat in the SUBMITTING queue for about 5 minutes, then we got a message that an officer was reviewing it, followed shortly by the initiation of a video conference. The officer could see us, but we only got audio from the officer.

- We selected the voluntary Verified Traveler program option on the app which resulted in a very short video conference with all onboard. Each person had to hold their passport open to the picture page alongside their face as the CBPO officer took a picture.

- The only question asked was where we planned to travel and for how long.

- Shortly after the call ended, I received an email with our clearance number and each crew received an email with their new Verified Traveler number.
