WPLMS WooCommerce Subscription Integration plugin issues or platform issue

Hello, i have a problem with WPLMS WooCommerce Subscription Integration plugin. Woocommerce Subscription made a major update these days and i have the following problem: when i change the next payment date for a subscription, the student gets expired course status allthow the subscription is active. For example: i have a course that starts on 30th of nov. Students enrolled to the course since 2-3 weeks ago, waiting for the class to begin. In the mean time, the subscription time is aproaching second month order and to avoid that, i changed the subscription next order time from 26th of nov to the 20th of december. The subscription is active but the students now cannot acces the course and probably will not be able to acces the course till 20th of dec when he can make the second online payment ... So...i can you please help? Thank you very much for your time. anca bogdan
