Here is my feedback after uploading a video on 3speak android app you can confirm the video is visible ony profile and is published.
This is a great app and especially helpful for existing bloggers on hive.blog so it has a well established existing audience. Please add 4k support, advanced analytics like real time stats for views per hour and last but not the least remove auto written text like .MP4 from video description. 1080p video rendering works fine.
You can clearly see my introduction post on my hive.blog account hopefully I am eligible for the reward for feedback.
