How I can acquire a new serial number for my Delphi 10.3.2 Community Edition?
I did ask Embarcadero support, but haven't answer yet.
It's been fixed by Embarcadero on 27/11/2019. You have to request/register to download latest version 10.3.3 and the email will now contain a new License if your old one has expired (not sure if license has not expired but you do not have to re download if you have downloaded 10.3.3 already). It will not update License for earlier versions you must get latest version, seems fair.
