This has already been reported here.
We're still waiting on some kind of resolution. The delay is rather annoying, as it's pretty much entirely torpedoed my project until we have a fix for it.

This is very unfortunate. I found that turning off the "scene management" in NetworkManager solves the problem as alternative. I hope this helps!

I hadn't tried that. It works! Thanks a ton, I can actually get back to work now!
You should leave a comment in the other issue about that, it may help narrow down what the bug is.
