Unity Engine

Hi All

I have an app in ios. It was developed in Unity 2018.3.7f1.Its working fine. I have an playerprefs in my app to identify how many levels are user played in my app. The problem is while updating my app the level started from beginning. Its not started from where the user last played.

So my question is Did Playerprefs are deleted while updating my App?

How can i Avoid it?Where i can store playerprefs that it should get deleted while updating my App?

Thanks in Advance

Simple google search will give you this answer here.
I would check the places you update the PlayerPrefs, you might override it.
