Audio Recorder not working at all in Opigno (Drupal 8)
I do not know whether it is a bug with Opigno 2.x (tested up to 2.4) or incompatibility with Drupal 8. Anyway, you can create an audio recorder activity, but it is not diplayed at all. Not even a blank space. Just no frame for this activity.
From what I can see the version of Audio Recorder is 1.0.14.
If I import H5P example, the effect is the same.
