I’m using the Zoom Room Controller SDK (C++) to control a Zoom Room, but I’m facing a couple of issues:After pairing successfully, the room sometimes gets unpaired automatically without any callback. I only realize this when I call a function and it returns result code 11 (which means not paired). To fix this, I call RetryToPairRoom(). Sometimes the pairing works, but other times it returns error code 100000401. In this error state, if I operate the Zoom Room using the native controller, I receive all the callbacks properly. However, when I try to perform any operation through the SDK, it still returns result code 11 (not paired).So my main problems are:Why does the pairing break automatically without any callback, if something like logs file or other are required from my side please let me know? Why does re-pairing without an activation token sometimes return 100000401, and even after that, why do operations still fail with result code 11 despite receiving callbacks?

@Tanish Luhadia , while there are a few of us lurking here, most folks working with Zoom SDKs and APIs are going to be more active in the Zoom Developer Forum - I suspect you’ll have better luck getting a response there.
Spoiler alert - the ZRC SDK is generally under-utilized, so it still might take a sec to get someone who has direct experience with it to weigh in!
