Attaching screenshot of the iTunes Connect page with form for the demo account.

A demo account is also required for TestFlight as in attached screenshot.

Eric, please create an E-mail account and provide some credentials for: TigaseAppDemo@tigase.net so I can setup an apple demo account.

It's not an email account. This is XMPP account for testing/reviewing our client by Apple. Daniel, you can register an account for these tests yourself on tigase.im.

added demo account to app page, however I cannot edit any Test information under TestFlight. I believe this is only available to developer or admin roles inside iConnect.

Ok, this is for Andrzej then. Andrzej, please copy all the information prepared by Daniel from the main application page to the test flight. There should application description, demo account, and other data.

Done. %andrzej.wojcik please review just in case I missed something.
