Purchased the H9 today. Plugged it in. Had the app already on my 4S. Got the bluetooth pair up. Registered per the app's instructions and clicked on the verification email. Went to sigh on and got and error message that said
false false false
EN-US X-NONE X-NONE
“The stompbox challenge in your request was invalid. Please restart your device while holding the hotknob button and right footswitch to clear settings”
Tried it numerous times, reinstalled the app, everything….anybody else run into this issue?
