Not receiving emails from Instagram to reset password, or my own ATT email
I have been locked out of my Instagram account which is linked to my ATT email because I forgot my password. When Instagram sends me the reset link, I receive no email (yes my email was spelled correctly because I have been able to reset in the past this way). There is nothing in spam/junk/other folders. No blocked domains or contact or filters or anything like that. I never use this email except for a couple social media accounts since the email account is over a decade old. I tried sending myself an email from myself (ATT email) and received nothing. I tried sending myself an email from gmail and DID receive that one, so I know it’s still able to receive some emails.
Any tips on this? I’ve tried the troubleshooting options that ATT offers on the help pages etc but nothing is helpful and I can’t find a contact to speak or email someone directly about this.
Thank you for any help or tips.
