Hi. I saw the following feature: if the video was uploaded via the Android mobile application (the format is not particularly important, I tried mp4 / hevc H.265 / H.264 / 4k / FHD / 30/60 FPS) it will be played through the same application. If the same video is downloaded via a web browser (or via a local network), then it will not be played “File type not supported” … perhaps this will be corrected.
