My App Store suddenly started showing “Cannot Connect” immediately after I verified my Apple Account. It doesn't work on Wi-Fi or cellular data. My internet works, VPN is off, date/time is automatic, iOS is updated, Media & Purchases works normally, and I already reset Network Settings. Please check whether there is an issue with my App Store/Media Services connection or Apple Account.
