I tried to work with fresco for the last few weeks, and finally I am giving up.
It crashed lots of times when undoing several steps. It was not due to any high cpu or ram usage. There was still plenty capacity left.
Then I tried to reinstall fresco and Adobe creative cloud. Before that, I made sure that all my work was synchronized and uploaded to the adobe cloud, and fresco told me so.
But now after the reinstall all of the duplicated versions of my sketch (i duplicated the original file to save my progress in steps) are missing. so I lost a lot of progress.
There is nothing in the "deleted" folder.
I am using a Microsoft Surface Pro 6 (i5, 8gb ram) with all the latest drivers and windows 10, and the latest fresco free version.
I just wanted to let you know about these bugs. Unfortunately this app is definitely not save to work with yet.
