Short answer. If Instagram approved a step and then says the account is not found, save the approval and the not-found screen. Try the username, the email, and a device you used before. Send us both screenshots. We do not stop at one appeal. If Meta ignores it, or the ban gives no reason, we send a formal legal notice and bring in lawyers.
Account not found after an appeal is a second screen, not the appeal itself. People finish an ID check or see a review move forward, then the login says the account cannot be found. Platform Actions has logged cases in this shape. Save both moments.
Screenshot the approval or the selfie confirmation, then the not-found page. Note the username you typed, the email you used, and the time. Try instagram.com and the app. Try the email address on the account as the login, on a device you used before.
Send both screenshots. We file through Meta’s official channels, with support chats and follow-up emails, when there is a route. It takes a few days. Start on the contact page. We never ask for your password.
If Meta ignores you
One appeal is not the job. We file through Meta’s official channels, open support chats, and send follow-up emails. If Meta ignores the appeal, or bans the account with no reason, we send a formal legal notice and bring in lawyers. It takes a few days. We never ask for your password.
