Thanks for posting in the Community. I'm sorry to hear you're having trouble with the PDF links within your document. Just to verify we're on the same page in regard to intended functionality, would you mind reviewing our Help Center article on Actions (Links) and Hotspots? I'm currently having trouble reproducing what you've described. As this seems to be an account/document specific issue, would you mind contacting us here with some example Lucidchart documents and the resulting PDFs which do not have the links that you expect?
