Safari tabs

I have reached out to Apple support multiple times to no avail so I figured I’d try my luck with the community and see if anyone else has had this issue.

I recently purchased an iPad eighth generation coming from an iPad Air two which I still use for my kids. I also have an iPhone 11 Pro. I am somewhat savvy with iOS and troubleshooting but can’t seem to figure out the issue I am experiencing following setting up my new iPad.

In Safari i like the feature where I can hit the tabs button on the top right and see what other websites are open on my other devices. I cannot get that function to work on any of my devices anymore. Apple support was confused and clueless thinking I was trying to get the handoff feature to work but that is not the case, it is simply the tabs in Safari is not showing up across my devices. Does anyone have any remedies or have they had any experience with the same issue? I have literally tried everything, restarting all my devices, signing out of iCloud, and even resetting my iPad to factory settings and re-logging in.
