Hey there, thanks for providing answers to the questions I had. I’m glad that you found a workaround by introducing a transient multicast delegate.
I understand promoting those SL actors to NSL is not always an acceptable solution, especially with your use case. I’ll give feedback to the team regarding detecting incompatible binding (NSL binding to SL) resulting in warnings earlier. But since you are unblocked, I’ll close this case - respond here if any questions remain though. Thanks for sharing how you worked around this.
