Hallo. My sub is up to date and I am logged in (Apple ID) on my Samsung phone and Firefox and Safari browsers (Mac Ventura). Ads are showing only on Safari. How do I get rid of them? Thanks in advance 
I’m sorry for the trouble.
I think there’s a good chance that you’re logged into different accounts on safari and other devices.
In safari and any other browser, you can visit here to determine the subscription status of your current account: Etymonline Premium
