Apologies for the problems with the Add block function from the block library as well as the drag-and-drop issues. We would need more information in order to investigate the issue. Can you please provide your domain name and version information for the plugins and WordPress? Providing access may also be necessary for us to be able to investigate the issue in more depth. rid plugins are up-to-date and WordPress is updated. Make sure that all of your BoldGrid plugins are up-to-date and WordPress is updated. Remember also that BoldGrid is a series of plugins for WordPress. If you have loaded another theme editor or plugin, it is possible that a conflict may exist with that plugin. Disable your plugins (except the BoldGrid ones) one-by-one to see identify any plugin issues.
If you have any further questions or comments, please let us know.
