Why did it happen?
Flexpa released a fix to accommodate a scenario where some payer authentication flows were incompatible with Safari. However the fix, which uses cookies to handle communication between Flexpa Link and Flexpa API, introduced a bug which was undetectable in the development environment because the development environment shares the same domain across services.
How do we prevent it in the future?
Broaden test suite across browsers. Safari, Chrome, Firefox etc.
Test across multiple domains in the development environment
