If users are seeing different numbers of interventions, it is likely due to the approval status of the hubs attached to their account.
When one hub is approved and others are still pending, the user will only see interventions linked to the approved hub.
Once all hubs are approved, the number of visible interventions will stabilise, and related issues should reduce.
This is intended functionality and ensures users only interact with interventions that are fully approved for their assigned hubs.
