If loading chats twice on different folders --> How does updates / 404 work?

[bossdeep]

I have 2 chat folders:

• ChatListMain has 9 chats.
• ChatListFolder (chat_folder_id: 2) has 4 chats.

Then, I load chats in this sequence:

Loadchats (ChatlistMain) --> 9 chat updates are received (as I expected)
Loadchats (Chatfolder id 2) --> 9 chat updates received (Shouldn't this be 4?)
Loadchats (ChatlistMain) --> 404
Loadchats (Chatfolder id 2) --> 404

Is this expected behaviour?

Thank you @levlam

Yes. 404 is returned for loadChats when all chats from the chat list are known to the app already. updateNewChat can be received any time for any chat.
