@Kent Sun could you please share the client-request-id and timestamp from response headers for the request where the API does not return private channels.

I created standard and private channels via the GUI or Graph API, and then I tried to use Graph API to list all channels(v1.0/teams/team-id/channels), but sometimes the private channels can be obtained, sometimes not, and there is no problem with the standard channels. After about 10 minutes, all channels can be obtained stably.
