Yeah, this is such a bummer, why have form software and email field format, if the form doesn’t actually do anything from setting that field type. Seems like a relatively easy push for Airtable to implement.
I feel like Airtable Forms are very much second-class citizens, in that they just need a tad bit more work to make Airtable a great alternative to most form software. But it hasn’t seen any update in years.
