Why is that?

[Chamod1]

I have note 9 and how is this possible?

[Shiv9564]

Uninstall and reinstall it. Perhaps it's synchronisation problem...

[Chamod1]

I can't download it.

[Hacky]

I'm using S8 and it's totally fine on my phone.

[Chamod1]

Note 9 Android Oreo... Doesn't work on mine.

Clear data for Google Play Services and Play Store from all Applications segment then try again.

[Chamod1]

Done... No joy. Doesn't work.
