Issue Summary

We can observe that for huge spaces, the report may have already finished and the file uploaded, however the User Interface still show as running, with the download option not available. 

Steps to Reproduce

1. Select a big space, for instance, with ~45000 contents
2. Go to Space Settings > General > Legacy Content
3. Select Pages and trigger the "Export to CSV"

Expected Results

We can observe the report running for some time (longer due to the size of the space) but eventually we will see that it had finished, showing "Your exported zip file is ready to go!" and the "Download CSV" button is enabled.

Actual Results

The UI remains stuck and the "Download CSV" is not enabled.

Refreshing the page does not show the option also

Workaround

Currently there is no Customer workaround for this behavior.
