Can't download from Materials Explorer App

The Export options in the Materials Explorer App don’t work for me.

Steps to Reproduce:

  1. Open Materials Explorer App
  2. Log in via Github
  3. Search PbO2
  4. Check a few boxes on the right (not sure if this is even required to export)
  5. Click ExportCSV

Nothing happens
