This is how I sign in: https://forums.opera.com/.
Upon signing in, the first page has the category list on the left.
The Avator icon shows 'Edit Profile' but that does NOT take me to the link that you provided!
'Edit Profile' and 'Edit Your Opera Account Profile' are obviously different options and it is the latter that I cannot find.
Can you walk me through it, step by step, after signing in and seeing the Categories list?
after i turn on VPN i stuck on infinite loading tab.
I have been waiting for this to come for a year already. I haven't really found a smart way of using Ecosia without going to its website first.
The whole idea of using Ecosia is to produce less carbon emission (by using renewable energy sources) and to use the money to help forests. If I have to first type/search for Ecosia (an extra search/energy consumption), it loses partly its purpose.
Then, you would try asking to their Social media managers, I've found them some time ago on the Opera website if I'm not wrong.
On the Forum, even for questions about the browser itself are no official answers.
