Fixed the following 3 issues.
- Large Word, Excel, and PowerPoint files with embedded videos and other content could fail to import or Preview even when within the limit (100MB), but they can now be imported successfully
- When sending a message in a new Chat and navigating to another screen while a response was in progress, the screen could revert back to the Chat afterward, but it will now remain on the screen you navigated to
- In the AI Chat sources, clicking on a different page of the same PDF would not navigate to that page, but it will now navigate correctly
