What I've noticed with it was the built in security within the eero would block ads, but that means it blocks video from playing that have ads built in before it - like say, an ESPN player. So I went to disable that site-by-site so it can open up college sports sites (Which have trackers built into their freaking drop-down menus). Sometimes when an ad wants to play a video to get to the next step, that causes things to hang. I use the Brave Browser for MOST of my stuff (on a Mac) and don't have any issues with unnecessary ads. I will turn the brave shields off for some sites, like things that need to save specific logins, etc.
