Hey @Cagatay Goncu, thanks for reaching out and I'm sorry for the delayed response!
Since you've already tried both normal and incognito mode and still see "Your request has failed," it's worth trying the following:
Try a different browser (or a different device)
Disable any ad blockers, privacy extensions, or VPN browser extensions temporarily.
If you're on a work, school, or otherwise managed network, try switching to a different network (like your phone's hotspot) to see if that changes anything.
I can see you’ve already reached out to our support team (ticket #1984713), someone from our team will follow up with you there soon.
In the meantime, if you get a chance to try any of the above, let me know what you're seeing (and which browser/OS you're on), that'll help speed things along!
