I just tried to order some spare parts in the online shop, but after clicking “place order” I just get redirected to a page that says “Invalid request”.
After trying a few times I got a mail with the subject “Welcome New Fairphone Customers: Please Confirm Subscription”, even though I’m not a new customer:
Okay nevermind, I found the culprit. The browser addon Temporary Containers blocked information from the FP store to be transferred to the site I get redirected to.
Now it works.
PS: Even with all self-protection addons disabled I still got the “Invalid request” message at the end of the whole process, but now I got a confirmation email, so I think it worked.
