+1 even though they are on the battery „not optimized” list, these apps keep deep sleepingI'm experiencing problems with push notifications.
When i leave the phone in standby for some time it will stop notifying. When i pick it up again, i'm getting push notifications that are several hours old.
And when not in standby push notifications are inconsistent. Especially for all facebook related apps like whatsapp, messenger and Facebook itself. Maybe Zuckerberg related but my old Android 5 Asus tablet is always reliable receiving the same messages instantly.
