Hello Camilla Motte,
Thank you so much for your question. First we request you to check our theme demos to know is that works on your mobile device or not. After that, if demo works fine, please check once by deactivating the installed plugin. If that not worked again, please check the added Google Ads is responsive code or not. First make sure, the adsense code is responsive or not.
Let us know your site URL so that we can check it with the best possible way as well.
