We are having issues with our Login with Amazon process. It works on Chrome and Firefox but not on Safari. On Safari (desktop OSX) the Amazon login screen just reloads after submission. On iOS Safari the browser redirects back to our website but the user is not logged in.
We are using a plugin through a Joomla CMS website but the process works fine in every browser but Safari. Here is what happens on desktop: https://tutorial.evolutionnutrition.com/qGuXyyjw
It looks like there is an issue with the headers in Safari but there really aren't too many details in the console that tells me anything.
I tried to attach images of the console but apparently the forum post form fails if you add images, lol. Edit: Adding images after creating the question seems to be working.
I have contacted Amazon Developer Support twice now but don't seem to get any response.
Anyone aware of any settings that break Login with Amazon?
The user is created on the Joomla website but the user is never redirected from Amazon.
