Newbie to Newbie, When you say crust do you mean the edge or center? What flour are you using?
IMHO Starting off making Neapolitan 🍕 in an Ooni can be trying. My neighbors had a hard time. They eventually
lowered the temp, started using a 50/50 mix AP/High gluten and make a more NY style pie. It seams to be working for them.
