Purchase wont sync with app

I have a premium subscription to MLB tv plus an MiLB subscription. I had no problems with the MiLB app last year. This season, however, it will not recognize my subscription. Whats the point of subscribing if the app wont let me watch any games?
On another note, fewer teams are participating in MiLB tv this season—make sure the teams you want to watch are available before you subscribe.
