I wanted to mention that in order to look into this issue it is still important to receive an example of this which occurs naturally in your app, since it is needed in order to design an appropriate fix and to assign the fix a priority. So far, there has never been a bug report of this occurring “in the wild” because it was designed to be an improbable event, so it would be good to get a real example of how it occurred in your app in a form that prevents the pause token from being used, in order to understand the first case of it appearing as an issue.
If your app reads different sources, just let me know about a source which leads to this issue — you can also inform me by email in order to keep it private.
