title: Update Installed App in subsites from tenant in sharepoint online
body: <p>I would like to update the existing app which is already installed in my sharepoint subsites.
  The app is deployed in Tenant site. Now I needs to update in subsite rather than go and click &quot;Get It&quot; open in each subsites.
  I needs to update using PNP Powershell script.</p>
  <p>I tried, with below command, to Install the app</p>
  <p>Get-PnPApp -Identity abcd-adfbd-xx-yyy-uu | Install-PnPApp</p>
  <p>the app is installed in all my subsites. However, I wants to update the app by using pnp powershell i got failed
  becz, I used this below commands</p>
  <p>Get-PnPApp -Identity abcd-adfbd-xx-yyy-uu | Update-PnPApp</p>
  <p>Update-PnPApp -Identity abcd-adfbd-xx-yyy-uu -Sope site</p>
  <p>no use. Please share your idea, how to update the installed app in each subsite using pnp powershell</p>
  <p>Thanks,
  Britto</p>
