I’m also a mod, and it broke for me.

See this discussion: https://www.reddit.com/r/help/comments/1d4d8bc/reddit_down_on_official_reddit_app_and_boost_not/?rdt=42748

Both ‘small card’ formats appear to be the same size on my device.

I went back and selected ‘default’ icon in the settings and the duplicate one was removed.

Looks great. Suggest that the backup file have a unique name so it is not confused with the Boost for Reddit backup.
