My Whiteboard is Lagging or Delayed
Lagging or delayed whiteboard can be likely due to connectivity issues. Make sure that you have a stable internet connection and that you're using the most recent version of your browser. You can check out the network and device requirements here.
If you notice a lag while drawing on the whiteboard while using a graphics tablet, it is likely due to a compatibility issue with the browser and the tablet. Lessonspace supports and has been tested with most major writing tablet brands. Check with the manufacturer of your graphics tablet as to whether your browser is supported. If you're using a tablet with wireless technology, please check if you have a stable internet connection and consider connecting your tablet via wire.
My students are not seeing the same part of the whiteboard
Please be sure to enable Leading mode, so that your students see what you see. Note that if your students are using Lessonspace on a device with a different screen resolution, they might see the whiteboard slightly differently.
