Unable to add a second account pointing to the same server

I want to create two accounts, my personal and professional profiles, both hosted on the same self-hosted Akkoma server.

Adding an account works fine for the first user, but for the second one I am not asked to add the account name but rather pointed to a url which authorizes the already active user.

Steps:

  1. Go to add account
  2. Select “Use an existing account”
  3. Add server URL and continue
  4. Open URL and observe that this link is for the existing/already authorized user

Expected: Ability to enter the a new user account, in step 3.
