Why a small delay necessary between master and viewer channel creations?

[lherman-cs]

In #98, we need to add a small delay before running the viewer. Otherwise, the viewer will get stuck in "Create Channel" signaling state. The log shows that the server responded with 400 even after the master could successfully create and connect to the channel. This seems to be an issue from the backend. But, we need to get further investigation to accurately find the root cause.

Do we use the caching provider?

@MushMal Yes, we're using the file caching provider, same as the sample.
