I'm getting this annoying ad as well.Mobile android.
The popup hovers over the top menu.
Sometimes it displays the ad and the menu under it. But mostly it hovers over the SB menu. So i cant click on the recent posts button, which is the only button i need.
Even after closing the app a white bar covers the SB buttons. SB is not usable for me at the moment.View attachment 716971
Gonna look into it when I get home.
