I have someone reporting that none of my messages show up while that person’s new Android (I think running 15 – whatever is most recent in Google line). When the phone unlocks, all messages show up. Battery management is disabled, no data restriction, and Delta is exempted from Do Not Disturb notifications.
Not sure what else to do, as nothing shows up in notifications until the screen is unlocked – other apps work as expected
This persists – my messages notify the user when the person unlocks the phone, no sound or visual shows up until unlocked. Which means time-sensitive messages never show up as intentded. Using chatmail w/push for both accounts.
