It seems Google really ignores Wikipedia in Bosnian language. Latest example is COVID-19 article that was present on Bosnian wikipedia long ago, but Google will not generate the box on the right. Wikipedia in Croatian has added COVID-19 few days ago, a much shorter article then on Bosnian Wiki, and visitor count has skyrocketed over at Croatian Wiki, while plummeting on Bosnian Wiki. I am not sure where the issue is, but hopefully we can find a solution in the long term.
