Reload Collection from Cloud
Since all of your Collections are stored on the cloud (WPR cloud or 3rd party), that means they're located somewhere outside your WordPress installation. In order to use them, you have to fetch them from the cloud first.
If you haven't been using the site for a while or you have modified a shared collection on another site you have to reload it
How to reload a Collection:
- Go to the Collections tab
- In the first card, find "Reload collections from the cloud" button and click on it
- Wait for the Collections to load
