Unable to see the Poll/Quizzes option on the meeting screen

For a few participants who are joining zoom meeting created by our licensed users, the option 'Poll/quizzes' is not visible on the Meeting screen. Majority of these users are using the latest Zoom Desktop Client version 6.2.3

This issue is also there for a few meeting hosts as well. The host is unable to see the Polls/quizzes button on the meeting page.

Note : Under Account Settings> Meeting > Meeting Polls/Quizzes, the option is enabled
