PNG files in InDesign not displaying properly

[Agnesse]

Hi,
can someone, please,  help me to solve this mystical issue?

Since I updated the last version of InDesign CC 2017, PNG files aren't displaying properly.
As You can see, I have normal .png file with transparent background, but when I import or place it in the InDesign CC 2017 document,
it have dark grey background under the image. Why is that?
In the Illustrator or Photoshop it shows correctly with transparent background.
Really looking forward for some suggestions.

No problem with InDesign CC 2017 with this transparent PNG:

The problem must be with the graphic. Open in Photoshop and save in a different format that supports transparency like PSD.

Hi,
Yes, I know, that I can open file in the photoshop, save it as PNG-24, and file will be displayed correctly in the InDesign with transparent background. But the problem is, when I use Illustrator and exporting for example 10 icons with transparent background. I can't use them in the InDesign directly. Earlier there were no problem with that, but now it's just waist of time to go always after each small icons to photoshop and save again. And the weird part is that if you open the same file in the photoshop or Illustrator or just in the preview screen, it looks like it should look with transparent  background.

what settings do you have for backgrounds in PNG-8 in export for screens?

[Agnesse]

Yes, I used the same.

Why are you exporting PNG from Illustrator? Save as AI or PDF and place those.

OK, after experimenting, I think that there is conflict between Illustrators "Asset Export" and InDesign, because, when I tried to export it from Illustrator  with the classic method File / Export / Export As... as PNG, everything works again fine.
