Maybe related to #5762 In this case the first chat is always with the default Assistant Jan with the wave hand emoji. Even if I renamed the assistant (the only assistant I have). But in my case, the assistant on the top is correct, but the assistant in chat is still Jan. Only when I click somehwere else and back to the chat, the correct assistant is than answer in chat. In this case, the initial post is from Jan and the second post from correct assistant. It seems that the app does not load the user data or initialize correctly.
