Arrayformula storage issue

Maybe I should rephrase. It’s not a non issue, but we are looking at the wrong thing. Yes, I hit end of the order sheet when adding to the cart and yes it created the 500 new rows, but the new rows were empty. Glide ignores empty rows. All it did was add 2 rows to the quota for the 500 row limit. My only thought is you have a formula or a script or something populating those new rows with data that I don’t have in my copy of your app. I couldn’t verify that in your GIF since you didn’t show all of the columns. Can you verify that the new rows are completely empty?
