We are currently working in Unit 6: Physical Computing in the CSD curriculum. We are on Lesson 6 at the moment. I have about 12 Adafruit Circuit Playground Classics and 12 Adafruit Circuit Playground Express boards. They have been working fine for two years and worked fine until we got to lesson 6. Today not one student could get their board to connect. We tried in the Maker App and also using Chrome with the Serial Connector for Code.org installed. Both of these have worked fine in the past.
Myself and my students are beyond frustrated. Adafruit doesn’t provide any assistance via email or over the phone. They only provide the forum which hasn’t been helpful. Any advice or guidance would be appreciated.
