I'm using Affinity v 1.10.1.1142
I'm relatively new to Affinity, but I've created several other graphics with Layers, and had them export to PDF properly. I have an Affinity file with two Layers, each with various layer items within. I've searched the forum, and found several other posts with the same issue, but I have yet to solve the problem based on suggestions from them. Exporting to a PDF results in a file with no Layer information. Any help or suggestions would be much appreciated. I've attached the affinity file and the resulting PDF. I'm sure I'm missing something small.
