Newsletter Subscription Process Issue Due to ATP Safe Links

[shopwareBot]

If double opt-in is enabled for newsletter subscriptions, users are supposed to confirm their subscription by clicking a link sent to their email. However, when a user with Outlook's Advanced Threat Protection (ATP) enabled clicks on this link, ATP modifies it for security checks. This modification can unintentionally trigger the subscription confirmation on the server due to ATP's pre-fetching of the link to ensure its safety. Consequently, by the time the user is redirected to the confirmation page, the subscription might already be processed, leading to a confusing scenario where the user sees a message indicating an error, even though the subscription was successful.
