I am using Microsoft Visio Professional 2016 64 bit and Adobe Acrobat pro DC Version 2021.005.20060. I am not able to integrate Adobe with Visio. If I need to create a pdf document from visio then I need to press "Save as" and choose the formate as pdf. This flattens all layers in Visio while saving as pdf and does not save data information embeded in visio shapes. While using 32 bit visio, I used to get save as Adobe pdf menu and option to save all visio layers and data information in pdf. Is there a way round ?
