So trying out latest 2020.02.10 (27) Build on android (xenhub).
1. The underline styling for the Plus Sign (Create New Thread) is not lined up correctly.
2. Required input missing node_id? (Not a friendly message and shows up even during forum selection)
3. There's a Lock thread option at the bottom? I can lock a thread as a user of your forum?
4. The workflow is the opposite of XF Post New Thread. In XF it's Post New -> Select Forum -> Type Message. With your app it's Post New -> Type Message -> Select Forum. This is going to confuse a lot of people.
