How do I update what kind of phone I have so I can do the Quick Match walking?

I received this email after submitting information about my availability to walk for Rover;

"Hi Aaron,

Thank you for your interest in Quick Match walking. Unfortunately, a smartphone is required in order to be a Quick Match walker. As you indicated you do not have a smartphone, you are currently not eligible to be a Quick Match walker. This is because the Rover mobile app is needed in order to accept walk requests, track all Quick Match walks, and to ensure payment to walkers.

If you purchase a smartphone in the future and would like to continue with the Quick Match certification process, please let us know.

All the best,

The Rover Team"
