It doesn’t lose the tabs at the end of the tab list, for you? Tabs just disappearing after being opened is a daily issue, for me.

I have nearly 1000 tabs open in Orion on my iPhone and have never had this happen. If they were falling off the front of the list I'd still notice the count going down.

I often see the inverse of this - tabs I've closed spontaneously reappear in later sessions. Wish they would put a little more polish into the iOS version, but for lack of better alternatives, I still use it.

I never have more than a few tabs open, so I don't see that.
