What do you mean the links start breaking? What links? What are you trying to accomplish?

- ScottWorld, Expert Airtable Consultant 

I mean the client-project links randomly unlink or go missing on shared projects.

Sounds like you may have some automations running that are overwriting your linked fields, probably because the automations are updating the Client record’s link to Projects?

Try looking through your revision history to see what exactly happened, it should point you at the automations that are doing this and you can update them from there.  Specifically, you’d remove the update of the link in the Client record and update the Project record to link to Clients instead, this way the each Client’s Project list will keep growing instead of the older ones being unlinked

If you look through the revision history and can’t figure it out direct message me a link to your base and I can take a look at it for you!

Are your clients sharing links to projects stored in an Airtable attachment field? These expire by design

One solution is to host the project files in a different location (such as your website or cloud storage like Google Drive / Dropbox) and just store links to the files in Airtable. Then the links will not change.
