When I exit Autodesk Sketchbook and Re-enter and try to undo it won't let me. I really needed help with this, i know this sounds weird but i did this for TikTok, an app for making short videos and making funny stuff. And if you want to know my account it's "Itsmejanas". So, lets start the story. I was doing a drawing on Sketchbook. And I accidentally clicked something to make the toolbar disappear, i was randomly drawing with no undo button so i searched up on google how to get my toolbar back. I did what it said and i got it back. Then i wanted to add a image. So I clicked Export (because i thought it meant export the picture) and it exited Sketchbook! Then of course I went back in Sketchbook so I could finish my drawing. And i looked up at the undo button. And it was there but it was grey, so when i clicked it. It didn't work! Please Help!
