I was trying to make jpeg backups of my art, and I found that it was taking too long. Using a smaller folder with 4 artstudio files, I confirmed that I could export the folder. It took a few seconds. When I then chose the jpeg fomat, the export went on without end, until I cancelled after 15 minutes. The same thing (interminable process) happened when I chose the heic format. I am working with current IOS and artstudio 4.1 on an iPad Pro 13" gen 3.
Anyone else see this bug? Is there a workaround? Are the developers aware of this?
