Hello to answer the questions in order here:
- For quick reply: When you receive an incoming call with your Surface Duo that is open to one screen, the ability to reply to the caller with a quick text response can be done by tapping Reply. This option is not currently available when you are using both screens.
2. When you are dictating text are you pausing more then about a second between sentences?
- There is currently no pinning chat options in the messages app.
- I have just reproduced what you are mentioning with the Outlook RSVP dropdown and am currently researching this.
Thank you
