At this time, Pro and Plus monthly subscriptions are the only plan type that can be paused, annual plans can not be paused. A pause allows you to take a break by temporarily removing your Pro/Plus access for a set number of months (1, 2, or 3 months) without needing to cancel your subscription. You will not be charged for the paused months.
As annual subscriptions are charged annually and you purchase access for a full year, there is not a way to pause.
For more information on pause, please see here.
In addition, pause is currently not available if you paid via PayTM.
