Can’t export as .ai file from illustrator app on ipad
I've been working on a file for a while and have been able to export as .ai previously, but now when I click export as ai the 'exporting' text appears and then just disappears and nothing happens. Other files are fine.
I want to save it and then scale it to a new larger art board to finish work on it. I've been working on a small scale as the tools I want to use come out better like the pencil for outlining elements of the picture.. It has over 60 layers at the moment and I don't know whether file size is the issue.
I have iPad Air 3rd gen.
any help or suggestions appreciated!
