You know the saying 'practice makes perfect' so keep that in mind
The world is an exciting place; you need to be more exciting than the sounds, sights, and smells of the outside world. Bring toys, treats, an upbeat attitude and lots of patience. Whenever you start something new you always start from square 1 and work your way up, so keep rewarding every glance, every movement you like so the dog will be looking to you constantly in anticipation for getting rewarded for those behaviours.
One thing I found that helped when I saw Delgado struggling with focus is stop, find a quieter place and take a break for a few moments. Get that engagement back and then start again, keep sessions short and always end on good notes and you should see good progress
