Hey, thanks for the report. This is a known issue. Scroll position isn’t saved when switching between chats. The team is aware, and your report helps with prioritization.
The main thread for this bug is here: Chat view scroll position resets when switching between conversations
About the second note on jumping while scrolling through a long history when virtualization loads more content, that’s a related issue and it’s being tracked too.
There’s no timeline for a fix yet, but the bug is logged. Let me know if you notice anything else.
