Under the Subscription tab, you can know how many users are subscribed to your plans. Navigate to the Subscription tab, go to the Total column, and click on the number displayed on each subscription plan. That number includes all Active users and Trial users. That will allow you to know which users are in each plan and change subscription-based issues for each user.
You can view a detailed breakdown in the analytics section of your Admin area. Click on See Breakdown to view a detailed report for your In Trial, Active, and MRR analytics.
Once you click on the number of total users, the subscription plan page will open up, and all of your users will appear. On that page, you can Search for customers, Export a CSV file with your users' data, resolve some subscription-related issues by clicking on the three vertical dots, and even access each user's profile page by clicking on the user's name.
If you want to search for a particular user so you can check their subscription plan or make some changes, navigate to the People tab, find the user, click on the 3 dot menu, and then click on Edit.
Then click on Manage Subscription. From here you can end their membership. You'll then be able to assign a new membership subscription.
