Can't view/toggle artwork layers in new Adobe Acrobat 2024

[ieshai12013471]

Hi there!

I'm currently trying to view an artwork PDF file (generated from Illustrator 2025) which has multiple layers (like Spot UV etc) and I can't seem to view/toggle them on/off like normal. I can view the actual "layers" panel but it doesn't display the list of separate layers with the "eye" icon contained in the document. 

I've even tried to disable the new Acrobat which downgrades it to the original Adobe Acrobat interface but still doesn't display the layers properly. I'm wondering if anyone has come across this issue since the latest Adobe Acrobat update (Nov 2024) and if there is a setting I need to change in order for it to work again? 

TIA 🙂

May be that the file has no layers.

Thanks Bernd, appreciate your response. The file does contain two separate layers. I've also tried to view other artwork files (which I've been able to see these layers in the past) and they now have the same result (no "layers" list).

Can you share a sample file?

I have an update/resolution to my issue - I worked out it was my oversight. I realised my PDF settings for saving the artwork out in Illustrator had changed. I wasn't aware the compatibility setting had changed from Acrobat 8 to Acrobat 5 - this then disabled the "Create Acrobat Layers from Top-Level Layers" option 🤦🏽‍♀️
