I'm quite annoyed with the update because I seem to be no longer able to save individual art boards as jpegs. When I go to export them, even when I change the setting to jpeg, the only option available when my computer files are opened in the last step is png. I was exporting this exact file one artboard at a time just fine before the update.
please note: any solution that saves all my art boards at once but as seperate files won't work. I use this for storyboards, so I use the export option to have very presice control.
