Can no longer add People to a chat and include chat history in Microsoft Teams?

Thanks for this post to let us be heard.
I have the same issue. I can add a person to a group chat and get the option to include chat history, but in a 1:1 chat it creates a new (and therefore empty) chat instead.
When a new member of the chat is added there should be the option whether to include the chat history or not, regardless of the number of previous participants of the chat.
I agree - the eventual mistake of adding to much history to a new member is the same in both a 1:1 chat or a group chat, so we need the option whether to include chat history or not in all cases.
Because, It is always the new member's need and authorization level that must be considered when adding history or not - regardless if there are one or many persons in the chat from the beginning.

Is this feature really intentionally removed by Microsoft (it seems too irrational to be intentionally) or is it simply a bug?
