Hi @Dave Knowlton FP, thanks for reaching out to the community! There are a few specific things worth trying when experiencing slowness:

• Can you try opening your document in a Chrome Incognito browsing session? This often improves performance by clearing your cache and cookies and disabling your extensions.
• Would you mind connecting to a different network or disconnecting from your VPN (if applicable) to rule out any connection or security issues?
• Having many page tabs, large canvases on each tab, and a high number of shapes on each canvas all increase the time it takes to load and update when changes are made. If you are working on a very large document, you may consider breaking it into several smaller documents to improve performance.

If the issue persists, please send the following information:

• A screenshot of any error messages or pop ups that appear.
• Is this occurring with all of your documents or just one?
• A description of any document or other changes that happened leading up to this slowness.
• A screenshot of the associated Javascript Console output after reproducing the issue. 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).

Thank you for your help and patience!
