Yeah, I agree. I'm a bit puzzled by the reluctance to make the online mode
communicate with the server, which would presumably address these issues.
Can someone explain why not to do that?
FWIW I've initially argued against that, believing that we can address
those issues in some other way, and I'd love if that was possible. But
considering we're still trying to make that work reliably I think the
reasonable conclusion is that Andres was right communicating with the
server is necessary.
Of course, I definitely appreciate people are working on this, otherwise
we wouldn't be having this discussion ...
