It seems to me that if widespread mask wearing substantially reduced transmission, that should have resulted in a clear reduction in infections. There should be a cause-and-effect relationship.

Guess what.
You're correct.
That evidence does in fact exist.
"Canada demonstrated higher mask compliance and more comprehensive universal indoor mandates compared to the United States, where policies were fragmented and heavily politicized."
"Mask mandates are associated with a 25% or larger weekly reduction in new COVID-19 cases in July and August, relative to the absence of mandates." cepr.org
"the United States has suffered nearly three times as many reported deaths per capita and has demonstrated considerably wider-ranging subnational outcomes than has Canada." www.tandfonline.com
Even within the Untied States, greater compliance with wearing masks reduced the spread of COVID:
"We find a significant and substantial effect"mask mandates reduced new weekly COVID-19 cases, hospital admissions, and deaths by 55, 11 and 0.7 per 100,000 inhabitants on average. Crucially, we find that the effect of mask mandates depends on the attitudes toward mask wearing at the county level, with larger effects in counties more positively inclined towards mask wearing. Our results imply that mandates saved 87,000 lives through December 19, 2020, while a nationwide mandate could have saved 58,000 additional lives. These large effects suggest that mask mandates are a crucial tool to counter pandemics, particularly if accepted widely by the population." www.elibrary.imf.org
