Hi,

I faced exactly the same issue. I solved it thanks to the Stack Overflow solution. I copy-past the content of the solution, step by step:

If you haven't setup CORS in your firebase console, Follow these steps :

Go to Project Settings in Firebase
Click \"Service Accounts\"
Click on link \"Manage service account permissions\" (this will take you to Google Cloud Console)
Click \"CloudShell\" icon on the top menu
Once CloudShell starts, run the following command (Use your bucket address from Firebase where your images are stored)
echo '[{\"origin\": [\"*\"],\"responseHeader\": [\"Content-Type\"],\"method\": [\"GET\", \"HEAD\"],\"maxAgeSeconds\": 3600}]' > cors-config.json
Apply the CORS Configuration to Your Storage Bucket
1. Replace YOUR_BUCKET_NAME with your actual bucket name. You can find your bucket name in the Firebase Console under Storage.
2. Copy the bucket name in the format gs://your-bucket-name.
3. Execute the following command in the Cloud Shell terminal to apply the CORS configuration: gsutil cors set cors-config.json gs://YOUR_BUCKET_NAME
Verify the CORS Configuration
1. To check if the CORS settings were applied correctly, run the following command: gsutil cors get gs://YOUR_BUCKET_NAME

All images added to the app have disappeared and I can't solve it... Firebase is working normally.
