Ah ok, got it, by any chance, did this device not come with Google Play installed or did you install a custom rom?
What you can try is to install a different webview, like this: https://play.google.com/store/apps/details?id=com.google.android.webview.beta
You can then change the default webview provider. I am really not sure if this fixes your issue, but might be worth a try.
