After updating YT studio then I didn't see the thumbnail edit option in my mobile app. Please advise me how to solve this problem and this future is very important to me. I also re-installed this application and tried but no luck. Please guide me on how to resolve this issue. Why is it not appearing in YT studio before updating the YT studio? It was working very fine on my mobile but when I updated the application the thumbnail edit option itself disappeared. How to rectify this problem? I really need this thumbnail edit option in my mobile application. Please help me and guide me ASAP. Awaiting for your replies. Thanks and Regards. Lakshmikanth A.G
