Some customers experienced blurry images that couldn't be downloaded across all clients, affecting files uploaded before a recent file storage update. We deployed a fix restoring proper file access, and confirmed it resolved the issue for affected customers. We apologize for how this incident affected you and your business. We will undertake a full investigation of the incident, establishing the technical trigger, the underlying cause, and preventive action to avoid a repeat in the future.
