hi @SyedSaifAli Product for Realm here. Unfortunately this is not a use case we test for and therefore do not support. I’m sorry about that - we need to do some in-depth research and generate a proposal to support. It is looking like it is going to be a pretty involved project and therefore a long-term project which is currently not on our roadmap. We will be sure to update you when we add it to our project plan.
