Thank you for posting in the Developer Forum. Thank you for the question, not familiar with Parcel but I am happy to check internally to see if there are any best practices we can offer. In checking the sample repo, I am not seeing how you are generating a meeting SDK signature. Please let me know if I am missing something.

Hi Donte, thanks for taking a look.

Correct I am not generating a signature, it is not required to see the issue so I removed that code from the sample repo for simplicity. Simply including the ZoomMtg object and building causes the problem.

I’ve seen other users with the same issue posed here so I suspect it’s not just related to Parcel.
