The link you requested contains an activation code that we don’t know.
Maybe your email address has already been confirmed, so that you do not need to activate it anymore. In this case, you should be able to log in to the Stitchies app.
If this is not the case, please check if the web address you just opened is exactly the same as the one we sent you by email. Please note that the URL is case sensitive.
If you have any problems activating your Stitchies account, you can always contact us via the contact form.
