@Christian_153, I'm not sure how indicative this V1 or V2 is. Maybe I don't understand when you think this change would happen.
I have a Family subscription. One account is used as the family account under which the subscription is purchased. My account is different but in the same plan. The family account has shared folders to two other family members with their own account, mine being one of them. Since at least mid-December, the shared folder from the family account has shown in mine as a linked folder, which has been a disruption. The link was restored at the end of April after I returned from overseas.
My Settings > Options shows Restore... at the bottom, so V2? In our family account, it showed Search. I thought it would show the V2, assuming the righting of the linked folder in my account to a dynamic folder was due to the family account having been migrated. I then clicked Search to see what was there because I have never used it, and I noticed the Search item in the menu disappeared. I clicked back to Restore... and realised there was no way back to the contents that were under Search. I had not clicked on anything in the content area of that Search menu, but it no longer exists, at least for now.
