title: SharePoint Online 365 and Web Site Title changing using CSOM
body: <p>I have site created in SharePoint online. Changing the title using C# CSOM code updates the title of site and same gets retrieved properly.</p>
  
  <p>But when I visit the site/refresh the site newly changed title is visible but again refreshing the page shows original title.</p>
  
  <p>How this can be fixed.</p>
  
  <p>I also tried changing title using "SetSiteProperties" function from - 
  PnP-Sites-Core/Core/OfficeDevPnP.Core/Extensions/TenantExtensions.cs</p>
  
  <p>The function SetSiteProperties throws exception. The site whose title needs to be changed is siteCollection of type TeamSite. 
  Using CSOM or PnP-core, title change works only for Communication Site. 
  For teamsite tile change is not working. Using CSOM it changes temporary only and with Pnp-core throws exception.</p>
