Amazon fire 10 can't display Hubitat webpage gets white screen

I have an Amazon Fire 10 tablet that was working fine the other day until it got disconnected from the network. After I powered it off then back on and I started Fully Kiosk Browser it would not display the Hubitat home page. It would work fine on other webpages but for the Hubitat page it presented only a white screen. I did get a message that the Android Webview is out of date. Has anyone experienced this before. I can use firefox and get to Hubitat just fine but prefer Fully Kiosk Browser.
