Flashing H & M advert

[24Dogcuddler]

I keep getting a flickering/ flashing H & M advert at the top of the screen. Really annoying and distracting.
When trying to close it down it keeps opening the
H & M site.
Anyone else?

Posting again. It really is making the site unusable now the H & M advert.
As soon as I close it down it’s back. It’s the flashing that’s so annoying and distracting.
