Hi @Ronald_Thornton! Sincere apologies for the delay in responding.
What you are saying is correct. This recent change responds to the new Proofing update we are currently rolling out Proofing for PDF . You can learn more about this feature in the following Guide article: Proofing in Asana | Product Guide • Asana Product Guide.
As you have mentioned, you can still zoom in, rotate or Print your PDF by downloading the file. I’m really sorry to hear this new feature has affected your current workflow. I’ll make sure to escalate your feedback for the Team in charge of this update to consider this pain point for future updates.
Apologies again for the delay in responding. Please let me know if there is anything else I can help you with!
