Ipad iOS 10.3.4 & Touchable Pro v.1572 - IT DOESN'T CONNECT

Hello guys,

I have problems with my touchable pro and ipad, I’ve been working (WIFI ALWAYS) with the app for two years and everything was perfect until now. The app doesn’t detect neither connect to ableton in my mac. The connectivity status is empty.

Please I need to work, can you help me? Thank you so much
