I have a problem. I don't know how to open the made board that I previously saved in this format. I remember exactly how it could have been done before. I saved the board as csv file, then I could load it and it looked like I made it. Now, if you try to open the csv file, it does not open as a board, but as plain text, despite the fact that I had diagrams made there. If anyone knows how to open it so that the board is unchanged - please write. If possible with screenshots. As a last resort, if this is not possible, please write how to save the boards so that you can reopen them later. Thank you.
