Armed away keeps changing to armed stay

[Ambreenh]

Hi. I have seen a lot of posts and no solutions on this. 
every time i leave home i arm my sensor away  and a minute later i get the notification that it flips to armed stay. Any idea why this happens and what’s the fix? Thanks!

Hey @Ambreenh is there a sensor that may be preventing the system from arming away? Please send us a private message so we can look into this
