[Problem/Question]
I’m using the Group Channel Collections with cache.
When server delete one groupChannel, it will keep in cache if the app is not in progress. And then I open the app, I’ll get the 400201 SendbirdException when query the groupChannel’s messages.
I want to remove the cache groupChannel when I get the Exception.

Sometimes it’ll get delete callback when open the app in next time, sometimes it’ll always keep in cache.
