Yes I did. I will call my mobile provider to see if any changes were recently made.

I originally didn't suspect a SIM swap attack as I received a text message from one of my contacts around the time the e-mail address was changed. I was out of town of course and did not have my data on. I saw the Twitter e-mail notification the following day. Checking with my mobile provider will be a safe bet for sure.

Thank you for the info.

I thought about this a bit further. Wouldn't the join date of May 2019 on the account [0] signify that the user may not have actually reset my password/e-mail address but rather created a new account?

Ether way, I am still going to contact my mobile provider to be sure.

Maybe the attacker simply changed your username after gaining access, paving way for them to register a new account in that name.

That's a good thought but I don't think that's the case unfortunately. My e-mail address is not associated with any Twitter account at this time.

Twitter states they cannot find an account with my e-mail address if I try a password reset. As far as I can tell, my previous account has vanished as I mentioned in my OP.

After changing the username, couldn't they change the email address too?

When they take over your account they do a forced delete and create a new account. That way they "own" the name and it is much harder to get back.
