All of my tables turned into sheets without me interacting with the 'convert to sheets' button in any way, and there doesn't seem to be a way to convert them back into tables.
Hi @Evelyn, I can confirm that that button is only visible when converting from tables to sheets. The button disappears when switching from sheets to tables.
My co-worker messed around with the interface earlier today until he managed to switch it back to table view, but we have no idea how we managed to achieve this.
