I have seen multiple posts that come back to the same source issue. Unfortunately it appears none of them reached the 100 likes before a year. Family plan allows multiple concurrent streams only if using separate accounts for each stream. If family plan allows six accounts, why is it necessary to have all concurrent steaming to happen under six different accounts? This is fine for individual phone streaming, but it isn't practical to setup all shared type devices such as car or in home device to each have it's own account. You also lose your play history, library, etc if you have to program each to it's own account. Many other services like Netflix base on number of streams regardless of logged in account. Please consider this enhancement as it seems only fair.
