Hi,
So this is very likely IOS Chrome related. I’m using lambdatest.com, but it shows correct on their VMs, although I am not sure if they have the latest chrome subversions installed.
Can you please try our demo page as well? Use the same “zzz” phrase on the main search there, it should yield the same no-results box.
I am really interested if this replicates there, it might be a generic issue then.
