Adobe's latest release of Illustrator, v 26.3.1, gives an error when using the Datylon export feature to upload templates to the online Datylon Report Studio.
So if you are using the Datylon export feature (In Illustrator menu Window > Extensions > Datylon Account), please do not upgrade to Adobe Illustrator v26.3.1.
We are working with Adobe to get this fixed as soon as possible.
Please stay tuned. We will publish any new information on this page.
