Buggy timeline

I have a stick-up cam. When viewing footage by sliding the timeline. It works and randomly it just stops playing. Even if I press pause and play it just does not play at all. The only way for me to view it then is to go to history and view it as events in a list. Or if I want the timeline view then I have to close the App completely. Seems very buggy and annoying.Anyone else experiencing this? is there a solution to this problem? I'm on the latest Android version on a Samsung S20+ device.
