Hi there @AnchorWHAT . Thanks for your patience with this. The problem seems to be that some ads are unable to distinguish between Tablet and Mobile so they are showing up in the middle of the screen on tablets in between content (as it appears on mobile). We're still trying to fix this but it's proving to be a bit more time-consuming than we had thought.
Could we ask you to try Mumsnet in a different browser and let us know if the problem persists then? And anyone else who's still having this issue, it would be great if you could do the same. Give it a go in another browser and let us know here if the problem seemed to remain or not and which browsers you were using.
Thank you!
