This app has not failed me yet, so I came back for answers with my most recent problem. I went to print a new file today with my Creality Cr-6se and noticed that the file that I had just downloaded was not on the screen. I tried downloading it multiple times,with different names, and even tried a completely different file. Nothing worked and even some of my former print files have been removed or are no longer showing up on the printer screen. I do not believe that it is a problem occurring with the sd card. I say this because all the files are on the card when plugged into a computer, they are simply not showing up on my printer screen. If anyone knows how to fix this, or have any ideas to help please share. Thanks!
