This was our highest priority issue as soon as we learned of it. We immediately put our development team solely on this issue and are happy to report that a fix was released by the end of last week. Please let us know if you experiencing difficulty with timing out and/or data retention. Meanwhile, we will continue to work on an even more robust auto-save feature that will ensure you can have a lesson plan in editing mode for multiple hours, should you need that much time, without losing data.
Out of these discussions with users, who were primarily teachers, we also learned some new things, as always, about the Lesson Planner in general and how it can best serve teachers. We plan to incorporate this feedback into our development going forward. If you have any thoughts about the Lesson Planner or STAR Online, please share.
