Occasionally, the input box may turn red, and an error message will appear, indicating that Clevr has denied your request to save.

This typically happens for one of two reasons:

1. The connection between your device and the Clevr server has been interrupted, possibly due to periodic drops in your internet connection.  Please ensure that your internet connection is active and stable.
   
2. Clevr is open in multiple tabs within your browser. To ensure data integrity, Clevr only supports use in a single browser window, preventing data from being saved when multiple instances are open.  Please ensure Clevr is open in a single browser tab.
