Hi @gam3r @Derek,
Thanks for reaching out with your concerns! Please be advised that we have a very strong Policy against auto redirects and popups. We have already taken a number of preventative steps in addressing them.
If you are on an older MoPub SDK, we highly urge that you update to our latest SDK release. This is because we have made several updates to prevent popups and auto-redirects from happening when served from the MoPub SDK. This means the update will stop popups and auto-redirects not only from MoPub Marketplace but also from any Server to Server or Custom Network (JS) that you may be working with.
Our Support Team will also be happy to review your Charles logs replicating the issue so we may further investigate the escalated creative. Please make sure to share the logs as an attachment with a description of the issue to firstname.lastname@example.org so our team may better assist you with the problem.
