Not sure how broadly you're willing to draw the borders around "non-local" but I'd argue most quantum physicists take Bell's inequality to suggest that hidden variable theories are impossible because something non-local isn't happening.
The real problem is we don't have an analogy for what actually happens, because - by everyday expectations - the traditional interpretations are beyond weird. And the more recent interpretations are even weirder than that.
It's likely - after Bell - that there's something non-local happening. And after this paper it's likely that whatever it is may not even be compatible with a stable identity for the observer.

Which seems to be arguing that instead of many worlds, there are many observers - not just simultaneously, but sequentially.
In other words, it's our belief in a consistent self with stable memories that may be wrong.
