Connection to Apple

Since logging in via e-mail won’t work starting 16th of September, I’m looking for an alternative. I tried connecting via Apple numerous times and it keeps saying I succeeded, but when I check my profile, I see the connection doesn’t stand.

When I connect my Google- mail, it does stay connected.

How can I fix this?

Which announcement did I miss?

Okay, I am the stupid one here. You won’t be able to log in using your username and I guess I jumped the gun thinking that using your email won’t work either.

Thinking about it logically, I should have known.

Yes I meant username. My bad!

I tried connecting through mobile, desktop,… nothing works. It has never said I was “connected” even though I get a notificiation that it worked.

Normally the “connect”-button should change to a “connected”-button where you can press it again to disconnect. It has never done that for me. It just keeps saying “connect”.

I was not trying to be sarcastic; I did not see any announcement at all (so also not about usernames).

Can somebody tell me where I can find this?
