Q: all images show error on loading even when uploading new images
I used to use this all the time and want to use it again for a campaign to my clients today and my cards are missing the images, and all templates are also missing... please help, as I have a campaign I want to launch! Thank you! I also just sent a free test card from your site but the image is also missing... The images do not display:
inside CardClan
in test emails
on desktop
on mobile over cellular
This confirms the image URLs are not publicly accessible.
Please check that:
Images are hosted on a public CDN
URLs do not require authentication
Links do not expire
Images are served over HTTPS
When opening the image URL in a private/incognito window while logged out, it should load. Currently it does not.

I’m getting a Firebase auth error on signup/login:
“First argument to verifyIdToken() must be a Firebase ID token string.”
This appears to be a backend auth flow issue where verifyIdToken() is being called without a valid ID token. I’m seeing it consistently across devices and browsers.
