Renew National Permanent Residence Permit in Hungary

I wonder if anyone has started this process, mine will expire so I submitted a application on the Enterhungry website, selected renewal option, attached a portrait pic, scan of current passport and current engedely card.
Submitted it with not further atttached docs.
It did give a warning that all docs are not attached but it shows as submitted and I can't amend it anymore.
I seem to remember you just have to tell them it is covered under the withdrawal agreement and it will be streamlined with not further proof required.
I guess when they review it they will ask, if there are anymore docs required or they will processes it as is.

My ID card also expires on the same day, but I wanted to do the Permit first because last time I had to renew the ID when they replaced the permit due to a printing error on the card.

As I understand it, you are correct that you need to mention you are covered by the Withdrawal Agreement and it should be a relatively simple process. I don't know anyone who has gone through it yet, so good luck, and keep us updated!
