I have noticed that on Safari 15 on both iPadOS 15 and on macOS I have noticed that I have iCloud tabs showing on the new tab page that aren't open on my other devices. The issue is tabs showing from my iPhone where there are no tabs open but it is showing random sites from over the past year. Some of them are ranging from Summer 2020 through to about February 2021. I right click and close them from my Mac but eventually they all reappear. Any ideas?
