No sound/beep on gear limits - Di2/SRAM

While beeps/tones on gear limits with my Di2 and SRAM gearset works just fine on 1040, I use them finding it very helpful... that isn't working on 1050 at all. The "Tones" option is enabled (I've tried disabling it and enabling it again as well) but makes no difference if it's enabled or disabled - it does not work for me. Please fix it :(
