Description

On the web version, the topic box is hidden on channels where topics are disabled (i.e. general chat only). On this mobile client, the topic field is available, and setting the value results in an error.

I think it's much more intuitive to hide the topic box on mobile in channels that are general chat only.

Research direction
Check the stream settings data structure and conditionally hide the topic input field based on the topics policy field from the API.
