The recently released version 3.1 of SEB for Windows exhibits a peculiar problem with MathJax content in Moodle. The formulas are first rendered, but vanish after a few seconds, and are replaced by an error message.
With version 3.0.1, this does not happen, please see the file attached.
This issue is most likely related to a CORS problem in SEB 3.1.0, which will be resolved with version 3.1.1.
