I've meant to request this feature for a while, I think it's one many glaring oversights of the Tapo app. Say I want to rewind by 10 seconds to "watch that bit again". At the moment one has to first zoom in on the timeline, being extra careful not to swipe left/right using ones sausage fingers, so as to not move away from the current playback time. Then, once fully zoomed in, one must swipe the timeline by 0.00001 µm to the right. If you go over just a tiny little bit you will rewind by 2 hours. Eventually you just wait for playback to catch up because it's quicker to just wait than to manually locate the one bit your wnat to see. This is by far and away the camera viewer's biggest UX issue.
