Ads are covering my iPhone screen

[DrinkFeckArseGirls]

The top of the sccreen is taken up by ads (Boots, Persil?) and I can't for example flip the thread nor access my account or profile details. When i click the "x" on the ad, it asks me if it was covering the page, I click it and then a new as appears.

Hi DrinkFeckArseGirls - would you be happy to post a screenshot of these?
Then we can send them over to the Ads team to take a closer look.
