The link unfurling result is cached for 30 minutes. There doesn't seems to be any way to switch off the cache.

Prasad_Das-MSFT&nbsp;is this still true that unfurled links will be cached for 30 mins with no way to turn it off?I see in the message extension result there is a cacheInfo object that has a cacheDuration and cacheType properties that can be set. What are the possible values for the cacheType property?
