Good morning,

Can you give me some more details about what you are experiencing? Is it possible that the app needs to be updated? Or are you speaking about a very specific function that isn’t working? I’d love to know more details so that we can assist in figuring out what is happening. 

What are you having trouble with? Is the app not opening? And can I ask if the issue you’re having is with the Lucidchart app, or Lucidspark?
