Signals Notebook: "Too many elements..." warning message is displayed when uploading a large number if files to an experiment

When uploading numerous files (more than 30) to a single content page in Signals Notebook, users may encounter a message stating: "As there are too many elements in this content page, [number] of them are not showing. Use the left side panel to view them."

Cause: This is not an error but a notification about the application's display limitations. Signals Notebook is designed to display 30 content items at a time on a single page. This limitation is implemented to maintain optimal performance and prevent excessive loading times. When the number of content elements exceeds this threshold, the warning message will be displayed.

Solution: Manually select the content element from the the left side 'Content' panel to view it.

Recommendations: To avoid the notification messages consider:
- Limiting uploads to fewer than 30 files per content page
- Creating multiple content pages to organize a larger numbers of files
