ie the tooltip does not appear after selecting ON in the Format pane. Regular tooltip works as usual.
I tried replicating the scenario from my end and the shared tooltip works as expected. Could you please provide the screenshots of the issue you are seeing and also the version number of the visual?
I recorded a short vid to show you that once enabled on a stacked column chart, for ex, the shared tooltip does not appear. Where can I send you this? I can’t publish a public link.
