I have 27 Bolts in my classroom and after break, my students keep getting a weird error. They will connect with the Bolt and after a few minutes, it will disconnect and the taillights will glow purple. I have made sure the firmware on all the Bolts is up to date and the students are using the most current version of the app on their iPads. Their iPads are running iPadOS 14.2. Any suggestions? We cannot get a lesson done.
