Hello,
as the title said I just sold someone my old iPhone 6. Before I sold it, I followed the steps on this website to sign out of iCloud and reset the phone: https://support.apple.com/en-us/HT201351
Now this person made a new iCloud address to sing into the phone, but they say they cannot download apps. I checked whether I am signed in to that iPhone, but I am not. What could be the problem?

This might be the problem of the person you sold the phone to. See What to do when the Mac App Store shows a different Apple ID for software updates https://www.macworld.com/article/3267709/mac-app-store-apple-id.html. This document refers to a prior owner, but is also applies to cases where a current owner's old Apple ID is the problem.
Basically, If an app is purchased/downloaded using one Apple ID, then you can't update/download it with another Apple ID. The app is inextricably linked to the first Apple ID. The purchaser of your phone will have to delete such and app and purchase/download it with the second Apple ID.

But, if you made a mistake, the phone still could the activation locked. If it is, then just give the purchaser the password, your password, that is associated with the problem Apple ID.

Have they or will they give you any details -- i.e., what happens when they attempt to download apps, including exact wording of any error messages?
Sold my iPhone to someone else, now they can't download apps
