I would like to inquire whether it is possible to revert ECHO 360 to the previous version (from 2023). Since the beginning of this year, all functionalities have become extremely sluggish. There is a delay of several seconds every time I pause the video. The subtitles on the right side continuously flicker up and down. If I switch to another page during playback and then switch back, only the audio plays while the video freezes, rendering it impossible to perform any actions. It takes several minutes to restore functionality. Moreover, there are frequent instances of sudden and permanent video pauses during playback without any warning. The pause button becomes grayed out, necessitating a page refresh and re-entry into the video to resume playback. Additionally, I am using the same network as I did last year, and there have been no changes to the network environment.
