Slow alerts on samsung android v9

I have a Samsung 10+ running Android v9. Garadget firmware 1.20. Don’t know what app version, but auto update is on. Almost always, there is a LONG lag between opening or closing the door and the notification that an even has occurred. Lag can be up to 1/2 hour. Anyone else experiencing this? Is there a fix?

Sometimes delayed notifications are caused by the battery saving functions.
