No Custom Expressions available

Custom Expressions are not available for me in Ask a question or directly from browsing the database. The attached pictures will show the field types as well as the two places we expect to be able to choose custom expression! I read through this post but I think I already have the correct field types assigned.

Thank You

Hi @scootscoot
Which version of Metabase? Looks like you’re using MongoDB, which currently doesn’t support Custom Expressions - go and upvote by clicking :+1: on the first post:
