touch ID failed
So recently my touch ID stopped working. I went into the touch ID settings and seen that it was turned off...when i try to turn it on it immediately tells me to "place my finger" like it normally did when i first registered...however this time it doesnt give me a chance to register at all...it jumps to a screen that says "FAILED. SORRY THE OPERATION WAS NOT SUCCESSFUL. PLEASE GO BACK AND TRY AGAIN" HEEEELP!
