Navica App worked for 3 out of 4 family members. Would not import tests results for the last person (me). It's okay as long as you don't need everyone in your party to have a test result to re-enter the country. Called customer support -- very nice and understanding. Made promises to investigate and fix within 1-4 hours. 9 hours later, still no NavicaPass despite having the results emailed to me separately 20 hours ago. Otherwise, for the other family members it worked great.
