Hello junsungE,
Many thanks for the response.
It seems currently on that first page of my account there is no subscription, however you can access it by going to Home | Microsoft 365 (office.com) the click on "Install and More".
Then it will open another My account page which is My account (office.com); Hence from this page you can access your Subscriptions as it used to be.
If you don't mind, could you kindly submit your feedback and vote in order to make this thread a top content and help any other community users who might be facing a similar scenario to easily find this thread/post.
Feel free to post back to the forum if any issue comes up and we'll be glad to assist.
Thank you for your time and have a great day.
