PDF as attachment in Planner

[Mgervasi]

I am able to attach a pdf to a Planner task and I see it in Preview but when I click to open it, all I see is a blank page.  I am on a Mac.

Same issue here. When you change to List-view, you will be able to open pdf attachment without issues. Only in Board-view this issue seems to exist. Should be resolved anyways, as it's not very convenient having to change the view to "list" for pdf attachments.
