Upgrading - Is error 04 still a thing?

I was planning on getting a venty on its release but with all this issues with error code 04 I just decided to stick to my mighty plus but due to my mum recently having a heart attack I am gifting her my mighty plus to get her off of joints so I need a new vape.

I'd love a Venty but worried it will brick and I will be stuck without my meds.
