Getting temp/cooldown bans for no reason.

Second time this has happened in two days I got a message while playing saying “The Banhammer has struck” and claims I was idling in match making which I was not. I’m not sure what I’m doing wrong I was thinking maybe its because I have my Pandora app playing music in the background on my console, Like I litearly finished a Mythic Snipers match backed out of the lobby to the game type selection screen and went to eat something I came back to my room and then I got the ban message, its only 18 minutes but still I shouldn’t be punished for something I did not do.

Post here for ban related stuff: https://www.halowaypoint.com/en-us/forums/e0d9938206f04a598ce84f2c8cadce02/topics/the-official-halo-5-why-was-i-banned-thread/19fa6556-e0b1-4248-b817-b3a99d0af5bf/posts

Thanks. Happy Haloing!
