Please note that Android is currently having problems with apps not opening and slow response. The problem is related to Chrome and WebView. Google has issued updates for these applications, however as of 10:40 AM EDT, I am finding it difficult to download from Playstore.
In the mean time, go to Settings and use the search bar at the top. Search for WebView and select it. In the upper right corner, you will likely see three dots. Click on the three dots and select "Uninstall updates". So the same exact thing for Chrome. Thus far I have seen 3 customers, all with the same problem, and this procedure got the problem under control.
