Just a caution in case there is an airtable bug. I made some changes to my airtable interface (below), and unfortunately the record detail page I designed is gone. It is just the default page now. I went to an old snapshot, and it was there. I reverted to the latest snapshot, and fortunately it was there as well. Sadly, I lost hours of work that I did since the latest snapshot.
Anyway, all I did before it disappeared was add some elements. I added a record picker, and two grid views. That is when it seemed to lose my custom record page.
It could be something I did. However, you may want to take a snapshot before you add any new elements to your page.
Off to rebuild everything I did last night 😞
