My biggest issue with the ad in the lower left corner is that the play/pause button activates it. This basically removes any ability to enter the "secret menu" that allows me to disable HDR, check signal strength, etc. I use this quite a bit, as my TCL Roku tvs do not have a strong enough backlight to be able to see some of the HDR programming. Until these ads arrived, I had just been able to use this menu to disable HDR and watch my show with the normal (and brighter) resolution. Now every time I try it ends up launching whatever garbage Hulu is trying to get me to watch.
I don't mind ads, as they are pretty much everywhere these days, but linking them to the play button instead of just letting interested users navigate to the ad and select is quite the oversight in my opinion.
Please find another way to activate this ad, or at least give us a way to temporarily disable it so we can use all the features we are used to.
