Hey
@fresh-library-57357, please get in touch with us through the support widget in the app. Question mark icon > Contact us.
Please send us the file you’re trying to upload, and the URL of the app/Workspace you’re trying to upload.
We’re also happy to look into any performance issues. If you can record what the experience looks like for you with a tool like
Loom, that would help us compare the experience you’re seeing with the one we’re seeing.
