# Collection membership delay

A collection lists its diagrams by asking Confluence's search index which diagrams carry its tag. The tag is saved the moment you add a diagram, but the index takes from a few seconds to a few minutes to notice.

Capable shows your own additions and removals straight away while you stay on the page. The gap only shows if you reload during that window.

## What you are seeing

* You added a diagram to a collection, reloaded, and it is not listed.
* You removed a diagram, reloaded, and it is still listed.
* The count next to a collection is one out for a short while.

## Work through these in order

| **Check**                     | **What it means and what to do**                                                                                                                                     |
| ----------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Open the diagram              | The **Collections** row in its **Details** panel reads the saved membership directly, so it is always right. If the collection is listed there, the change is saved. |
| What to do                    | Wait a few minutes and reload the collection.                                                                                                                        |
| What not to do                | Do not add the diagram again. It is already in the collection.                                                                                                       |
| Still wrong after ten minutes | Worth reporting, with the collection name, the diagram and its page.                                                                                                 |

## A few things that catch people out

* Someone who cannot read a diagram's page never sees it in a collection. That is permissions, not this delay. See [Diagram permissions](https://help.gocapable.com/diagrams/diagram-permissions.html).
* The same index also drives search, so a brand new diagram has the same short delay there. See [Template indexing delay](https://help.gocapable.com/diagrams/template-indexing-delay.html).
