I wonder if this is why the app I'm currently developing has suddenly started failing delivering both video and audio from the subscriber stream.

The app, which is stuck at the 2.15.3 version of the Opentok client, connects to the stream created by a client website, which in turn uses the 2.18.x version There could be some incompatibility between those versions.
What's weird is that the issue doesn't happen every single time, but it consistently occurs when accessing the client website from specific machines.

I might try to update the Opentok client version on my fork repo to see if it could solve this issue.

Yep, updating the SDK did the trick. In my case, I updated @opentok/client to 2.19.2 and native Android/iOS SDKs to 2.19.0.

I'm sending a PR for this, it'd be really nice if it could be reviewed and merged.
