How to upgrade my account

Hi? I would like to upgrade my account to Processing Exploration for 30 EUR per month to receive data from commercial satellites. Now I have trial. I am a volunteer and have started the development of a program that should process images from satellites also in high resolution. This research should also include machine learning. But the option to upgrade the account is not available in the account and the Upgrade button is obscured. What do I need to do to be able to upgrade my account?

Hi Oleksiy,
looking at your account it seems there are some additional data needed to ensure compliance.
Do check the banner at the top of the page in the Billing dashboard:

Already sent according to the banner… Here, answer

Here my letter

I am a volunteer and do not represent any organizations… I do not belong to any organizations

Did you upgrade your account? Because I have the same problem. I sent letter with my info over a week ago and got nothing till now. Why?
