I have long used my Ipad Air 2 to manage my two H9 pedals. Until recently. Presently neither my Ipad not my Iphone will connect to the pedals. The only thing which has changed recently is IOS.  Just today I bumped up to 12.1 and still no luck.  Anyone have ideas on where to go with this.

The H9 Control manual has some trouble shooting tips on these sorts of connectivity problems.  You can find it in the app by clicking on the Settings button in the bottom menubar and going to Help.  Alternatively you can also read it online: https://www.eventideaudio.com/support/downloads/h9-control-manual
