Hi, I have fallen a little behind with Metabox updates and as I feared now when I update I am seeing issues.(4.8.7 to 4.9.6)
I have updated all my extensions to the latest version (Conditional logic, group and term meta) which is fine until I update the core plugin, then I see that most of the custom fields lose their values and appear blank.
There are no errors from WP or in the browser console so I have no idea what the problem is or where to start.
Once the plug-in is rolled back everything is fine again.
