Sage CRM 2018 R2 - No Month View in Team CRM's Calendar?

Hi All,

Why there's no Month View selection at Team CRM's Calendar?

There's Month View in Team CRM's Calendar in Sage CRM 7.3 and below.

However, after upgrade to Sage CRM 2018 R2, Month View of Team CRM Calendar is missing. Is there any method to bring Month View back? Just like My CRM's Calendar?

Thanks and Regards,
Shandy
