I have a top-level publishing site. Under it is a teamsite. I specified a master page for my teamsite via the page <teamsite>/_layouts/15/ChangeSiteMasterPage.aspx
When I reload the teamsite it does reflect the master page I'm expecting to see BUT only for a few seconds. There is some kind of redirection going on because after 3 seconds the teamsite goes back into the default seattle master page look.
Please help and advise. I'm a sp newbie.
