I don’t think pin# import will bring team names from the registration form (yet?). You could get around that by exporting a CSV file from the web site and then importing that CSV into the match on device.
The team scores will show up when match shooters have some teams assigned and match settings specifies a max number of shooters in the team.
If you want us to look at it, email the match export file *.psc from device to support@practiscore.com or share link to the match results posted on PractiScore web site.
