Page with App Choice for Redeem code can't be reached

Hello everyone, please help!

I'm Adobe Contributor, and each year, I have access to the Plan for Photographers as a Gift from Adobe for their Contributors.

To reach a free product, I should use redeem code.

So, my steps are:
1. I should click on my unique link "here" in the blue ribbon.

2. I should choose the app I want on the page with a list of apps where I am redirected to the link from point 1. I will see redeem code.

Issue: I can't move from step 1 to step 2 because an error "This site can't be reached" appears.

I've tried that with two different computers (Desktop PC and MacBook). Also, I've been attempting with four browsers (Chrome, Firefox, Opera on PC, and Safari on Mac). I've tried with and without VPN. Any combination doesn't work.

Additionally, I personally know a colleague from another country who has the same issue right now, so the problem isn't unique.

I have reached Adobe support via chat and have explained everything in detail with screenshots. But, the first person dropped me to the "specialist who can help me better" from the "technical support" and explained again. The second person dropped me to the third, "who can help me better" from "billing support", and I explained everything again. The third person dropped me a link with a case/ticket creation form. I've created a ticket. They answered me fastly, sent a link to the help system, and closed the case.

After that, I tried to solve that multiple times by chatting and filling out the case/ticket form one more time. With all that insane rounding round experience of explaining the same things, templated answers from support via pushing the buttons and dropping me to the person "who can help me better".

How can I solve that? Look's like an issue definitely at the Adobe side!
How to escalate that up to the level of who can solve that?
