Does the column count affect the speed of the app and is there a certain number that limits ?
My main apps use tables (both Glide / GT and Google Sheets / GS) with 500-1000 columns. Speed is not usually an issue with columns so much, more there might be time latencies off you are writing values in and replying on these values to do things immediately (such as adding a row, then opening up a tab to go to that row).
I don’t have a right number, but in my big apps, where there are a lot of computed columns, that does affect things.
Yeah but my concern is in the column count in Google sheet so I suspect it loads the app slowly
