[CA] Wi Fish app with Wi-Fish system issues

I've got a Wi Fish depth finder and router working with an iPhone or iPad Raymarine Wi Fish app. After a lengthy sync, I get depth and temp, but when I try to set my transducer depth, the app quits. After starting it and getting a sync, the transducer depth setting reverts to zero. I re-downloaded the Wi Fish app today, am running the most recent IOS and just re-installed the 2016 Wi Fish software again.

I also notice the sync between iPad or iPhone takes anywhere from a minute to five minutes. I've checked to ensure Wi Fish is the only app running.

Cheers!
