Has anyone had this issue - beeps at the start/ end of intervals started to sound very low, iphone sound level set to max, music or other apps sound all right, just the trainer road beeps are very weak. Haven’t had that issue but started to get it last week. Haven’t changed anything in the setting.
Update - solved the issue. For some reason volume adjustment by buttons was disabled in iPhone settings, probably during update. Switched that on, all is working fine!
