Circuit Playground connectivity Issues as of March 12

Since this March 12 all my students started having connectivity issues with their circuit playground as we are working through CSD unit 6. I had the students download the maker app but many students working on chrome books are having issues still. Was there an update to Google Chrome security setting that is not permitting serial connector from working?

Did you see this post from last week on a related topic? If you have looked at this and are still having issues, you may want to reach out to to see if they have any updated information.
