Same here. Mine started ding that last night, after my S7 downloaded the latest Android OS update. Garage Talk and the forum operators need to figure out a better interface anyway. Functionality hasn't improved in years.
Unfortunately GarageTalk doesn't yet work on the latest Android OS (nougat). I know our developers have been working on a fix for a couple of weeks now, but I still don't have an ETA on when it will be released.
