Assalumualaykum brother. Arabic search no longer works on latest version. It worked before that.Try searching for the Arabic word "أتى" (without quotes) and you will see that that the app returns no results at all. This has been an issue that comes and goes with some app updates. Some update would allow for Arabic search without problems. Then, later update breaks it and so on. I will attach two screenshots one labeled new which shows the result of searching for "أتى" in latest version and another that shows the Arabic search working on a very old version. I am using Android 10 and latest update available from google store.

Regards.and thanks.
