In the 2.0.1 version of the new Meta Box AIO, all of my group fields that are set to cloneable=true have the add more button hidden with a display:none CSS property. How to ensure the add more button is visible?
I had the same problem after upgrading Meta Box AIO and removing the original Meta Box plugin. Re-installing the Meta Box plugin made the Add More buttons visible again.
This version now bundles Meta Box. You don't need to install Meta Box separately anymore. You can safely remove Meta Box (keeping it won't harm and won't cause any conflicts). This will help you shorten the plugin list and make things simpler.
There is a small issue with the cloneable button. Please activate the plugin Meta Box to fix the issue. The development team is working on it and the fix for this issue will be included in the next update of Meta Box plugins.
This issue has been fixed in the new version of Meta Box AIO 2.0.2. If it still occurs on your site, please share your site admin account by submitting this form https://metabox.io/contact/
I will take a look.
