I suspect that they've disabled this feature for everyone - it appears accuracy is also no longer shown for the big profiles. Probably takes up too many computing resources with how many users Chesscom now has to deal with.
There is an Insights feature where accuracy can be viewed, but it's for paid members only: https://www.chess.com/insights/hikaru#overview
This isn't the first time that features have been removed - Rating Deviation (RD) used to be displayed next to ratings, but now the only way to get those is via curl. I guess players not knowing their RD means they keep trying to chase their all-time high provisional ratings, etc.
Please look into this Chess.com. This is clearly very important and helps all of us in understanding our level of play every week or so.
