Hello, Still on the topic of precondition failure, the token might become invalid for reasons other than reaching the history limit of the server. For example, if a collection is deleted, then recreated, the server won't necessary maintain sync information about the defunct collection. Or the server may have encountered a crash causing the history information to be lost. Hence, we might want to change the overview section to be more generic: << In some cases a server may no longer be able to honor a previously returned token. For example, it may only wish to maintain a limited amount of history about changes to a collection. In that situation it will return an error to the client when the client presents a token that is "out of date". At that point the client has to fall back to synchronizing the entire collection by re-running the report request using an empty token value. >> Arnaud PS: about the collection recreate scenario, do we want to return a different precondition ?
