I couldn't find any account-related help, so I contacted Support and they referred me to this forum. I would appreciate it if you could tell me how to handle account changes in the Developer Zone. Best Regards f_Dsasaki About cancellation of developer zone premium account I tried to register for the Developer Zone Standard to obtain a license to use Questa, but I mistakenly registered for the Developer Zone Premier. I would like to cancel the Developer Zone Premier and re-register in the Developer Zone Standard.
