I just opened up App Store and the first screen is a full screen ad for Roblox. Then you scroll down and it’s 4 “now trending” ads, then below that another full screen as. The entire “Today” tab is a scroll full of ads.
That's why I don't open the App Store's first screen or the Today tab. I usually open the App Store to look at the release notes for my updatable apps. To find new apps, I use Google to find an app's page. A web-based search engine has blockable ads, the App Store app does not.
