Why can't I install viber on my windows phone 10?

[Windows Central Question]

I have a Microsoft Lumia 640XL and I recently updated it. But since then I have had trouble installing the viber app. I want to know why this is happening since I used to use viber everyday and it is a very important app for me.

Did you try restarting the phone, it helps in most of the cases
