Solved
The transfer market is unavailable in the web app.
Even after meeting all the access requirements, I still haven't been able to use the transfer market, which, unfortunately, remains closed despite my active involvement. I started playing at the end ...
Of course, I've visited this article's page many times. I play often, but it's a bit difficult without the app. I may have even received a notification that the market was open, but in reality, nothing was open.
