cant publish with classic update

hello, we have been using expo publish for few years, using a very old sdk (sdk 35), while we are also developing a new app at the same time.

Recently we try to publish another update to this old app, but it returns “Request failed with status code 404”.

I checked our last publish was on 2023 Jan 18. Want to know if it is server problem or something is deprecated. While I checked the timeline for classic update, it should support until 2024…

Thanks in advance.
