Utube ads in Japanese even though they should be in English

I have had this problem before: my ipad apps are not recognizing that I am in the US and need English as my language. An Apple representative helped me today with this, and I have noticed that several persons have had trouble with the same issue. Could you post the solution:

I had used TOR Onion browser to download a book and their vpn was activated. This VPN on the onion browser evidently directed me through Japan as one of the pathways so I ended up with all apps not recognizing that I am from the US and need English as the language. Once I removed all VPNs and reinstalled the one that I normally trust and use and have for many years, everything went back to normal. When using an Onion Browser, persons need to be aware that a VPN is often installed as part of that package. Thanks.
