@Paul Auclair​ :

There could be a few reasons why the import button is greyed out when attempting to import a .ipynb file into Databricks:

1. File format: Databricks does not support all file formats. Make sure that the file you are trying to import is in a format that is supported by Databricks. .ipynb files are supported in Databricks, but it's possible that the file you are trying to import is in a different format.
2. File size: Databricks has limits on the size of files that can be imported. Make sure that the file you are trying to import is not too large.
3. Access permissions: Make sure that you have the necessary permissions to import files into Databricks. If you do not have the necessary permissions, the import button may be greyed out.
4. Connectivity issues: There may be connectivity issues with your network or Databricks workspace. Try restarting your network or workspace and see if that resolves the issue.

If none of the above solutions work, you can try contacting Databricks support for further assistance.
