Record Details Not Available

What kind of interface are you trying to publicly share (calendar, record review, list, etc)? 

I think public, non-logged in users can only access one layer of record details (so in a calendar view, they can expand the date entry but other linked record fields can’t be expanded). This can be worked around in a few manners, by selecting the details shared on the cards or changing how the linked records are presented.

The easiest method to work around this is to simply add lookup fields from your linked records to the primary record folks are engaging with. 

Screenshots of what trouble you’re having is also helpful 😎👍

Exactly as mentioned by ​@DisraeliGears01! My approach is usually to create a nicely formated concatenation formula at the child record level, and then bring everything together at the parent record level with a rollup using Arrayjoin with line breaks.

In this way, you’d show the rollup on the interface, rather than the actual linked record field. 
 

Having said that, individual lookups would also work (but would not be great if you have multiple linked record fields).

If you’re open to a third-party solution you might want to check out the miniExtensions Portal instead.

With this option you wouldn’t have to add your external users as Airtable users in any way, since user access is controlled by a simple table in your base itself.  This gives you a lot more flexibility in who can access your data and what data they can see! There are also no limitations around the number of subforms within the portal so you can go as deep into the hierarchy as you like! 🤩

Thank you for your help everyone! The rollup worked and did a list instead of a grid. Everything shows up as intended!
