You were used to exporting unlimited guarantees via the Guarantees section. To avoid slowing down the platform, we have limited the exportation to 15.000 guarantees at most. If you want to export more than 15.000 guarantees, we invite you to use the Analyses module, which is more performant for huge exportations.
We have also removed the exportation form, so you can now export guarantees in one click.
See Export Guarantees for more details.
