I opened the ticket. Thank you.
Thank you for the swift response. Upon activating the 2FA, a pop-up appears requesting the code that I have been sent via email. I paste the code, 2FA is on and everything is fine. Until when logging in again and been asked for the code, but I never get that email with the new code. Tried this a couple of times, but I am happy to use another 2FA.
It will take some hours, before I will be able to try out Backuply again. Sorry for that, I appreciate your help.
