The Tag Groups Pro plugin adds further information to tags and posts and tracks any changes to them, if necessary. When you activate the Tag Groups plugin, tags and posts are migrated automatically. Since no existing data was removed or changed, your posts and tags still work with other plugins and themes. Even after removing Tag Groups Pro everything will be functional, although without the additional features.

However, sometimes you may experience that filters on the front or back end don’t show all posts. You can normally fix it with the “Migrate” button in the Settings: Search in the “Troubleshooting” section under the “First Aid” tab.

Running Maintenance also solves common issues.
