Mycelium wallet out of synch

[mknepper62]

Hello, so I have been using Mycelium app for several months on android with no problems. I simply deposit money at a btc atm and then send the btc from my wallet to markets and what not. Today every time I try to send btc after a couple of minutes the transaction says unable to broadcast because your wallet is out of synch. I have restarted my phone and the app, but have no idea what else I can do. Somebody please help me ASAP thank you so much i advance.
