Hi Guangda,
Thanks for the reply. I tried to reproduce this with our demo app but no luck. Did you override the following callback onMeetingNeedPasswordOrDisplayName (https://zoom.github.io/zoom-sdk-android/us/zoom/sdk/InMeetingServiceListener.html#onMeetingNeedPasswordOrDisplayName-boolean-boolean-us.zoom.sdk.InMeetingEventHandler-), if you override it, SDK will not show the password pop-up(some people do not like the pop-up), and will use the password passes in this callback to try to join the meeting.
However, if you override this callback, you won’t be able to join the meeting by clicking the notification. So something else might be not working. Could you provide the SDK log for us to further investigate? It will be hard for us to troubleshoot this if we could not reproduce it or do not know the log.
Thanks!
