On the TradeMe iOS app, a full-screen popup video ad appears shortly after opening the app (first time seeing this today), and when I close it out it automatically reappears every 10 seconds. The app is close to unusable as a result. The issue seems to have been addressed by completely deleting and reinstalling the app, but I don't have confidence that it won't reoccur. Seems to me like a new feature (full-screen, popup ads, annoying even when they do work as intended) was not tested on a wide range of devices before being pushed out.  Device: iPhone 12 mini
