Hi Rhiannon thanks for posting in the community! Sorry for the trouble you're experiencing with downloading your document - I'm happy to help!
Here are some specific things to check when exporting your document:
- Try the export in a Chrome Incognito browsing session. This often improves performance by clearing your cache and cookies and disabling your extensions.
- Sometimes issues like this can be related to internet connection speed or network security. Please try the export again on another network ensuring that you are on a strong stable connection.
If these tips don't help would you mind sending me the following details via this support form so I can take a closer look at the issue?
- The URL of the document(s) affected.
- A description of the download settings (file type document pages cropping quality etc.) that you selected for the download.
- A screenshot of the error message that appears when you attempt to export.
- A screenshot of the associated Javascript Console output. You can open your Javascript Console by pressing Ctrl + Shift + J (if your computer is a Windows / Linux) OR Cmd + Opt + J (if your computer is a Mac).
If anyone else has questions about downloading their documents please begin by reviewing this Export/Download Your Lucidchart Documents article from the Lucidchart Help Center and post any additional questions below.
