This issue is limited to Microsoft Edge. Someone flagged a file uploaded to a KnowledgeOwl trial account as phishing, which has since been resolved with AWS (the file and trial account were deleted). However, Microsoft Edge is now flagging all files uploaded to KnowledgeOwl as unsafe. We've submitted a report to Microsoft requesting a review. In the meantime, Edge users can help by reporting the site as safe.
