It is the load on the servers, to much traffic atm. I just tried again and it worked at the 2nd try. So just give it a new try and i am pretty sure it will work for you too. Regards Tom

Hi, i hate the new design too and i even can't work with that. I like to have my old Safari design back and a separate address bar. That new Safari 15 design drives me crazy and whoever did that should be fired. My personal opinion. You can try to get your old Safari back with time machine backup. Just go back with time machine before you updated to Safari 15. It should work. Personally i am thinking to switch to chrome now, cause Safari 15 is horrible with that new address bar in the tabs and tab groups, tab coloring etc. - to be honest it is the most confusing browser now, but apple will not go back to old design. They never do. You have to use it, cause they want it. The last changes of designs should be discussed. Those steps are not always good for the user. It is if you touch a perfect system and UI and got the most confusing result, cause you have the pressure always release something new and better. It is not better now, it is worst. Hope i could help you Tom
