Okay so let see if android webview is enabled or disabled on your device. Go into settings and you will find a search option on top, search webview and go to the apps info page and attempt to disable the app or see if there are defaults in the app that way.
If it is enabled and you cannot disable it re-enable chrome (you might want to make sure to update Chrome also) , then go into
Setting>developer options>webview implementation
You can set chrome as the default webview.
And if this option doesn't fix your issue then I'm sorry I couldn't be more help, and hopefully someone with a definite answer will see your post.
