I run Tabjolt to cache some Tableau Server dashboards. Some of these dashboards use the "Automatic" dashboard size. I have read that using the "automatic" dashboard size requires a new cache instance being generated when a user uses a dashboard size that doesn't already exist in the cache. At some point we will change the dashboards to use a specific dashboard size (instead of "automatic" sizing), but in the meantime I would like to know - How does Tabjolt caching handle "automatic" dashboard size? Does it cache at a specific dashboard size or sizes? If so, what are they?
