I have changed the Region at the bottom of Adobe Stock website multiple times from DE to English, but each day when I login and revisit the site... stock.adobe.com, the browser automatically adds /de at the end. I change the region to U.S. (English), and I get English, but when I do a search for a photo, results come back in German again. I have cleared cache, deleted cookies, tried different browsers - Mac: Safari and Chrome. Help!?
This happens because the country associated with your Adobe ID is Germany. There instructions here on how to change this: https://helpx.adobe.com/x-productkb/policy-pricing/change-country-associated-with-adobe-id.html
I'm having the same issue in Hong Kong. This answer only tells you how to change the region, not the language. All the other Adobe products seem to understand the difference, what's wrong with Adobe Stock? It shouldn't assume which language I speak based on my location. This costs too much money for this annoyance.
