Before OneUI 2 update "Windown" feature from the " Digital wellbeing" had an option to turn off do not disturb mode if we don't want it and only apply grayscale. Now do not disturb is included and it's frustrating because I do not wanna miss alarms. Yes I know that there's an option to allow alarms in the do not disturb mode.
@Adem0: Yes, Do Not Disturb features an 'Allow Exceptions' so you can keep alarms active while the feature is on. Strangely, Digital Wellbeing is missing from devices in our office which suggests it was a Google/Android feature that has since been removed from the stock updates, although it can be downloaded separately from the Google Play Store.
