Hi, I've just found out about this issue when I was trying to use my iPad with the last update (13.2.3) and my Sonic Port didn't work. This really sucks. Apparently every device would be left unusable and Line6 hasn't done anything about it. Too bad. I use several apps with sonic port (Amplitube, AmpKit+, Gadget 2, GarageBand, Cubasis) and now I have nothing to work with.
