Kieshi
I'm sorry for misleading you.
I think there is no video ID because such a phenomenon occurs with videos saved on my PC using DLNA.
Also, I have KEON and PowerBlow connected at the same time.
If so, I think funscript is not working properly. This is KEON's movement. (The stroke width is smaller)
When I connect KEON to DEOplayer's Bluetooth and connect PowerBlow to DEOplayer via Haptics Connect App, it seems to work without any problems.
