This is about the feature in Safari, that lets you see webpages open on other devices. I'll call it "tab overview" in this post.
I am using three Apple devices, a Mac mini, an iMac and an iPad. I am still on macOS Mojave and iOS 12.41.
I was used to seeing webpages open on my iPad, when using tab overview on the Mac mini.
After I started using the iMac, Safari on the Mac mini has stopped showing webpages open on iPad. Instead, it only shows webpages open on iMac, even when I am signed out of iCloud on the iMac.
This looks like a bug to me. Does anyone else experience this?
