Why can't I reply to a discussion on the Apple Support Community?

If the "reply" button is pale blue, the post is locked, like this one from 2018:

It seems you keep trying to answer inactive posts. None of us can do that. We cannot change that. Apple's playground—Apple's policies.

If you select a topic list from there instead of a search engine, your will see the latest posts. You can contribute most by working the most recent threads.

As I said in my previous response:

Long history here teaches that few people return to a thread they started weeks or months before to check for new responses. Your time here is best work working the most recent posts.

Even could you answer one of the ancient posts, I wager the odds f it being seen by the person asking are under one percent

Threads with this banner:

are locked due to inactivity, age, or both. Always look at the date of the thread, especially if you come here from a search engine. Search engines are notorious for finding old, inactive threads.
