Hi I’m experiencing similar problem. My App had an error asked me to reinstall on iPhone. I have my seed phrase. QR code everuthing. Sage as you. Saying invalid. Waiting and waiting for Metamask technical support to help but they’re too busy. So waiting snd waiting hoping I will recover my account. It’s shocking that the app is so unstable with all out money in the wallet
