There’s apparently a bit of a software fail for the LEGO company. When you launch the LEGO Boost app, it won’t continue until you’ve updated the firmware. It asks you to connect so it can update it, but it never actually updates. As I learned in this reddit thread, you actually need to get a different app and use that to update the firmware. Having to use a different bit of software while making you think the software you expect to use can handle the firmware upgrade is a HUGE fail in my book. Hopefully they fix this soon, but if they don’t -at least this resource can be here for anyone searching Google for the answer.
