At this time, only users with a rating of 4.0 and higher can gain access to create a subscription.
If your rating has not reached at least 4.0, you will not be able to create a subscription plan and users will not be able to subscribe to you.
To increase your rating, we suggest creating live streams or uploading videos and photos. Over time, users will rate your content and if ratings are positive then you should eventually gain access to the subscription function.
