@tw1t611 glad that worked!
@WardenCommander For the nested query I don’t think you need the upper level calendar the way you have described the relationship. I think your query should either be one of the two following based on how your data is nested.
In regards to updating nested data, most of my content we update from the admin UI so it is handled automatically so I’m not sure how to really do it currently. Because it is open source someone can probably dig into the source code to understand how the core function works.
