JOY WAS PREMATURE.
I can add more fields, that is true. However, there are still issues:
When I try to delete the added field (e.g. field number 502), the database crashes and I get an error (error is similar to the error in the past when I was trying to add fields beyond 500). See picture below.
Unfortunately, the moment I delete the field 502, it will also ERASE field 501. The field 501 is erased without my knowledge.
So before you start adding fields, please hold off. I guess this “Feature” if I can call it that way, is not available yet.
Makes me question if the 500 field limit is a limit based on the necessity (e.g. table speed loading experience for the end-user) or more of an arbitrary limit set by Airtable.
