Yep, Line 6 problem from the start. They knew about this in Beta For IOS 13,,,I use my ipad for 1 thing...MUSIC . Now I can't...I registered every line 6 product I own...Yes, c'mon , register your product. Give all your information. But when a critical update will cripple your Line 6 DEVICE, your on your own with no warning! You have my email, serial numbers from products that I own, how about, *Hey Sonic Port Owners...Don't update your IOS because we know your device will not be compatible".....I could have lived with Apple 12.4 . Didn't need Apple IOS 13. Now almost 4 weeks ....with a sonic port used for a paper weight. I have purchased about 5 to 6 guitar Apps from Itunes that CAN NOT BE USED because I have a non working guitar interface. Sorry to vent my frustration here....Thanks for listening...
