Is it a bug or is a new algorithm on Instagram after Changing the Email

Hi guys
has anyone experience this problem?
It happened to me on 3 accounts on different devices with differents IPs.
My account had been confirmed with email (for example Email 1) and phone number. I changed the email and confirmed my new email (Email 2) for Instagram. everything was OK but after a while my Instagram got challenge error confirmation:

Help Us Confirm You Own This Account
You'll need to verify your identity to confirm you own this account.

Email: f*******[email protected]

It sent the security code to the last email I had been confirmed.

Is it a bug or is a new algorithm on Instagram after Changing the Email???

This is a normal action not a bug just verify and move on no biggie also possibly you may have to many accounts attached to that ip address

I think its not normal. I changed my emails on other accounts and security codes never sent to the email I changed (I mean first email). they sent to new email that I have been confirmed. (I mean email which is set now in my account)

So are you can fix your problem? If can, please help me! I really need your favor right now! Because I'm facing the same problem right now! Please notice me as soon as possible. Thank you!

Happened to me once. This is why i stopped using temp email for the first regestrating. I lost one account because i didnt have the original mail box.

i believe it is a new algorithm. insta changes pneself every 2-3 months to prevent scammers
