Thanks for the response. The folders I share are really small (just a few KiloBytes). I also just created them for the test. It is also not entirely reproducibly. It seems like on some days this happens more often then on others. Maybe it's related to Dropbox workload. Is it defined from what size on a folder is shared asynchronously via the Dropbox Website? And if my small folder is shared asynchronously, is it really expected, that " files/list_folder/continue" will return a "not_found" error? Maybe it would be better, if it would return empty, how you described it ( and not with an error ). But actually I would expect the longpoll to respond _after_ the asynchronous sharing is completed, not when it is started. Then my " files/list_folder/continue " would not run in this problem at all. So the issue is not completely clear to me yet.

I have a few folders on Dropbox. I have a client app that observes each folder with "2/files/list_folder/longpoll". If a change is detected, I process the change with "2/files/list_folder/continue" . This is working fine so far. Now I encountered this issue:
I share one of these folders with another account via the Dropbox web site. The longpoll for this folder returns successfully and tells me there is a change. I call "2/files/list_folder/continue" with the latest cursor for this folder. The request returns with a response including the error tag "not_found".
My question is: Why returns Dropbox a "not_found" in this case? The folder is obviously still there if I'm looking at my Dropbox account, it was just shared.
If I repeat the "2/files/list_folder/continue" request some times (e.g. 3 times) in this situation, the folder is eventually found again. So there seems to be a small range of time after a sharing action, where "2/files/list_folder/continue" requests are not handled correctly. I first observed this issue a few months ago in April 2019. The issue did not show up in 2018. So is this expected behaviour or a bug at your side?
Thank you for your help!
