Did you not see Leo’s reply? It’s at the bottom of the thread.
I was talking about the potentially related issue that I linked that I have not heard anymore about.
And I was talking about Leo's response to that issue, at the bottom of the thread, which you never replied to and apparently still haven't seen.
This is the only Leo massage I see.
If it takes a really long time to list a folder, the tree will give up trying to sync to that folder (but it'll be cached once it does finally load, and work from that point on).
It shouldn't normally take that long to load a folder, though. If you're getting hangs, or local/LAN folders taking that long to load, something else is wrong and the tree issue is just a symptom of that.
That post is on this thread. We're (or at least I am) talking about the other thread, that you linked to, and that you complained you had not received any response to.
Leo's reply to that thread is here.
