Export As with Use Artboards now fully include all the object on the artboard and doesn’t crop them as expected
Something is terribly wrong with Export As.
For some reason 'Use artboards' no longer works in Beta 294.0.73 as expected. Here, I expect the parts of the circle to be cropped — but the resulting PNG includes all objects on the artboard.
Happens for other formats and multiple artboards.
This is PAIN.
Does not happen in GA build!

The latest Beta 29.5.0.15 has it fixed

Thanks, Egor. I realize I didn’t provide enough details earlier, but here’s what I can share:
I’m currently using Illustrator Beta. When I export an artboard to PNG using the "Export As" option to a Google Drive-managed folder. However, I’ve noticed that the same issue occurs even when I save the file to a local drive (Desktop).
I’m working in RGB mode because I need transparent PNGs. Initially, I thought the problem was limited to Artboard 4, but it turns out I’m unable to export PNG artboards correctly in random attempt. As a workaround, I’ve been creating a clipping mask the size of the artboards and exporting them as web files.
Here's the files containing all exported PNG artboards to a local drive as they are and the working .ai file, alongside with the setting I used when exporting. You can see the correct output (Artboard 1 and 2) and the error output (Artboard 3 and 4) when they all the same 1920x1080 in the working file.
Hope this helps
Thank you -
Can’t reproduce it from scratch :/
Please tell a bit more about these projects.
RGB or CMYK?
Do you export them in a cloud managed folder or not? Does it differ if you try another folder or drive?
Do these have raster images in them?
Does this continue to happen when you try o re-export these, or is it random?
There are so many things that can affect this... perhaps you can just share a project? Email it to sharewithai@adobe.com for the team to look at (in this case mention the link to this report, http://illustrator.uservoice.com/forums/601447/suggestions/49510841) or just attach it here in comments. -

Export As - Transparent - use artboard. All artboards came out ok but only artboard 4 failed to read the artboard. This happened in multiple projects.
