title: Flexdashboard (shiny) doesn't update with new data
body: <p>I made this flexdashboard: <a href="https://corona.berndschmidl.com/oesterreich/" rel="nofollow noreferrer">https://corona.berndschmidl.com/oesterreich/</a> which reads in data from Wikipedia and shows it. Till yesterday I was able to update the dashboard with restarting the shiny server. Now this doesn't work anymore. I'm aware that it has something to do with the cache but I tried everything I found here and on Google with no success. This is kind of important and therefore pretty frustrating.</p>
  
  <p>Any help would be really appreciated. </p>
