Thanks for posting in the Lucidchart Community! I'm sorry you're experiencing trouble, but I am happy to help. I was able to reproduce the issue you are experiencing adding links to boxes in your Org Chart. You will need to add the link to the text within an Org Chart in order to have the link/hotspot redirect you (see screenshot).
Unfortunately, you cannot currently add links/hotspots to the entire box shapes in Org Charts. However, we are always looking for ways to improve Lucidchart and your suggestions are the best way to do that. Do you mind adding your idea to our Feature Request Form? Requests submitted to this form are redirected to our development team for future product features and improvements. As a growing company, we take these requests very seriously and appreciate you taking the time to do this.
Please let me know if you have any questions!
