IntakeShield 0.4.3
Solve the signup CAPTCHA on the main thread. Zammad's CSP blocks ALTCHA's blob/data Web Workers, which left the widget retrying challenges forever.
Install via Admin → Packages in Zammad 7.x, then run zammad run rake zammad:package:post_install and restart Zammad.
See the changelog for earlier versions.
