Steps to reproduce the bug

1. Open a video
2. Change the speed
3. Close the player
4. Open another video

Actual behaviour

The speed of the 2nd video has not defaulted to 1x

Expected behavior

Since I didn't just open another video but I closed the player first it should default to 1x speed like the youtube app does

Device info

• Android version/Custom ROM version: Android 10
• Device model: Samsung Galaxy A30s

Like I said above the youtube app does this really well and would be very especially helpful when you play some music after a video you watched or something

This is intended behavior (which i implemented myself i think). #3288
There is an issue to save the speed on a channel basis #3621

Non standard setting (like speed 0.95x) could be shown for (eg. 3) seconds when video starts (as a reminder that speed has been changed last time/week).
