The new version of ArcPro 3.4.0 doesn't honour stand alone licensing. Updated version through the wizard and now it is stuck on the single use error. Created a new license provisioning file, tried to apply it and said already licensed. Open ArcPro again and still wouldn't work so needed to switch to a named user. This is on a headless server machine so we like to use stand-alone licenses for them. Not really an idea but didn't want to have to go through the million support questions to report it. I'll wait for the next update and try again and will used named user while I wait.
