Question about WordPress 6 compatibility

Hi!  Is the Photofocus Pro theme compatible with Wordpress 6?  We're running into an issue getting quote blocks to work and we're not sure if it's related to Photofocus Pro or Wordpress 6. In quote blocks created *before* the upgrade to Wordpress 6, the double-quote mark appears before the actual quote. After we upgraded to Wordpress 6, we can enter quote text but the double-quote mark doesn't appear. Thanks in advance!
