The schema for android_article_toc_interaction is shown in the mobile_apps directory but I'm unable to see it using Hue and get an error querying on Superset ("The table "analytics_hive.event.android_article_toc_interaction" does not exist. A valid table must be used to run this query.")
Please check if this needs to be altered to enable access. This is a low priority request, I am currently able to use data from the Legacy version - MobileWikiAppToCInteraction.
