This seems to be fixed now in 27.1.1 - thank you adobe!

@Kirk

I had to select the intertwined object and then go to Object > Flatten Transparency.

When I saved it as a PDF I made sure to have it compatible with Acrobat 8.

This seemed to work for me.

Hi all.. I tried the new Beta version, I tried using the Acrobat 8 compatibility and this does not fix any of these issues. Can someone tell me what I'm doing wrong, please? Or if this is going to be fixed. Thank you!!!!!

Still needs to be fixed.

FIX IT

Here is adobe's feedback on twitter:
Hey there, thanks for reaching out. Exporting Intertwined objects as raster is an expected behavior in Illustrator, and our product team is looking into it. Kindly upvote the uservoice you have shared and add your comments. This will help us prioritize this request. ^AM

Unbelievable. I cannot print and I cannot export as PDF when Intertwined. The big feature you guys touted at MAX. Was this even tested?

In addition to the pixelated graphic in a PDF, which happens the Save As... path as well as exporting for screens, when I open the PDF file directly in illustrator, it is still a live, intertwined graphic.

The intertwined graphic does not print either, it is just an empty space where the graphic is.

hi @adobe, is there any news? the tool is unusual for printing in this condition.

@Adobe, keeping in mind the Document Raster Effect Settings is actually the bare minimum.

problem not fixed in update 26.5.1

Rasterizes for me on PDF output, even with latest version. Tried a few different settings with no luck.

Did nobody at Adobe test export/save as PDF before launching this?

@Ravi Kiran
The anomaly in the overlapping area is separate from this bug. The Illustrator team should already be aware of this.

Overlapping portions break at certain places.

Intertwine applied object bug
・In the PDF area of Illustrator format files, applied objects are converted to 72 ppi low-resolution images.
・In the EPS area of Illustrator EPS files, applied objects are converted to 72 ppi low-resolution images.
・In X-4 PDF files, applied objects are converted to 72 ppi low-resolution images.
・In X-1a PDF files, applied objects are lost.

Workaround:
1. Select all applied objects.
2. Object > Flatten transparency...
Note that the Acrobat 8 (PDF 1.7) compatible PDF do not work around this problem.

「クロスと重なり」適用オブジェクトのバグ
・Illustrator形式ファイルのPDF領域で、適用オブジェクトが72ppiの低解像度画像に変換される。
・Illustrator EPSファイルのEPS領域で、適用オブジェクトが72ppiの低解像度画像に変換される。
・X-4 PDF ファイルで、適用オブジェクトが72ppiの低解像度画像に変換される。
・X-1a PDFファイルで、適用オブジェクトが消失する。

回避方法
1.「クロスと重なり」適用オブジェクトを選択
2. オブジェクト > 透明部分を分割・統合...
なお、Acrobat 8 (PDF 1.7) 互換PDFでこの問題は回避できない。

intertwined bug in photoshop when opening AI file. The intertwined object does not show correctly, like if it was in a so low resolution

PDF output is pixellated with all Presets - even with Acrobat 8 compatibility.
Also, overlapping portions break at certain places.

:D sorry haha

Sorry Marcel, I was joking, the pixel problem is solved because there are no pixels, it is empty with x-1a.

really? with what compatibility? when i save it as x-1a per default (acrobat 4 (PDF1.3) the file is empty.
