React-native-track-player: setRate() is not sync with notification centre's duration and current time value

Also noticing this when the playback rate is below a certain threshold

@krunalbad There's a number of things I've noticed.

• It appears to me that setRate() must be called _every_ time another operation happens on the track player: play, pause, next, skip.
• I've noticed that not only that but you must also use pause() then re-trigger the rate setRate() and then call play() again in order to get the Notification Player and UI Player to sync up, otherwise the Notification Player resets its rate to 1x. It seems to me like pause MUST be called to trigger the "remote/notification" state when updating the rate in the UI.
• Lastly, I've found that I had to add a pitchAlgorithm, otherwise the ratio of speed between the the Notification Player and UI Player were slightly different in which the lag was compounded depending on the length of the track.
• One other thing just to take note of is that setRate accepts floats like .1.6 but you'll notice if you console log getRate() after setting it, that the value isn't 1.6, but rather 1.600000023841858. If using state management probably best to store the value of getRate() rather than using a value from a variable like 1.6, but really shouldn't affect the experience either way.

Does it work for you? I have tried this but the issue is still persisting for me 😞
If possible can you share with me your piece of code of setupPlayer and updateOptions
