I'm living in a different time zone to my work's home office and need to be woken by emails arriving in the night (thankfully not too often...). On my old LG phone it was reasonably straightforward to set Gmail up to only notify me for work-related emails by using a Gmail label in combination with the Do Not Disturb function. I then set a custom song as the notification sound (rather than the short 'beep' alert sounds, which tended not to wake me up). On my Samsung Galaxy S7 I'm having difficulty with the last part as it seems impossible to set a custom sound (i.e. song etc. rather than choosing from the Samsung preset notification sounds) as the notification sound on Gmail. So: I can get the notification setup working fine, but need help changing the notification sound in Gmail to a custom file. OR a different workaround would also be welcome... Many thanks in advance!
