There is an erratum page that lists the main problem of each firmware release. Please visit if something goes wrong after you upgrade your device.
If you experience an issue with your In/Out device, first visit the troubleshooting and On Court Troubleshooting pages. Then fill the support form through the In/Out helpdesk.
If you don't own an In/Out and have a question, contact the In/Out team.
The support website is organized around five categories: Hardware, Software UI, On Court, Firmware Upgrade, Companion App.There is also the Logs and Roadmap.
