iPhone 11 bottom microphone not working

I just bought an iPhone 11 128GB, literally 3 days old. Everything was working fine, but I don't know if it was because of the update, the bottom microphone stopped working, meaning I can't contact Siri, I can't send voice audios to Instagram or Whatsapp, so that mic is kind of broken. All microphones are fine, the ones from the cameras, but the one for Voice Memos, that one, is not.

Is it related to latest update? Just updated to 14.1. Tried setting off Bluetooth, tried giving and not giving permissions to the apps, resetted it, cleaned it carefully with compressed air, I think I just tried all and nothing gave me a solution...
