Time ago I reported this issue, forum chats viewed messages counter got by UpdateChatReadInbox is always different from the official Telegram app

UpdateChatReadInbox contains the number of unread messages in the "View as Messages" mode. If the mode isn't enabled for the forum, then other Telegram apps preload 20 recently updated forum topics, combine their unread counters, and show the sum as unread counter of the forum. Currently, this isn't implemented in TDLib, but can be implemented on the app's side.
