Exporting Issue about AI

Hi, I am having the following problem. I am unable to export a file in AI format. The only export options are JPG, PNG, SVG and PDF. Pls let me know how to export to AI format.

My environment is below.
App Ver: 4.13.5
Device: iPad
OS: 16.5

Hi kunijiro When you try to do that, what happens? What exactly is the issue?

Thank you.

I also export using a.i. on ipad. Not sure it makes a difference but noticed you are on 4.13.5 and I’m using the newer .6 If that doesn’t work I found sometimes deleting and reloading the app may fix problems . Backup. Hope you get an answer.
