Failure of an app App won’t play content. Frequently closes and doesn’t save your last work you just completed. Just use a computer on web based application.
Not loading I get the following when trying to view a lesson: Error viewing content. TypeError: null is not an object (evaluating 'document.querySelector("#react").cl ientHeight') Has not worked in at least several days
Use desktop not app App often closes or doesn’t load. It also does not track progress or show full content. Suggest to use desktop only.
