I've seen it mentioned by the WeWeb folks that Airtable causes problems as a backend. Probably for several reasons. But, primarily, because Airtable doesn't store images in a way that they can safely/consistently be accessed through the Airtable API. I can't remember, but I think it had something with not having static file URLs. Anyhow, I assume this problem would be the same if you swap in Toddle for WeWeb.
I'm guessing there are folks here using Toddle with Airtable as a backend that have found a workaround for the file storage issue. Care to share?
