Since the last month or so, I have noticed Firefox Focus no longer blocks ads on certain websites. The ads are initially blank when the webpage is loaded, but when scrolling down and hovering over them, then the ads are eventually loaded. I have attached some pictures. For completeness, my version of Firefox Focus is 120.0 (17371) / iOS 14.6, and I have the following features turned on: "Enhanced Tracking Protection" as well as "Advertising", "Analytics" and "Social". Any advice would be greatly appreciated.
