Eleanor_Huynh I had already turned it on using edge://flags and selected for immediate sleeping. Now as this feature permanently rolled out for Edge, you can't even select the time out for the same. Even changing it again from edge://flags didn't affect at all. WTH!

    I'm checking and the flag is still available in Edge stable version 88.0.705.63

     

    so just go to the flags and either set this to default or disable it: 

    edge://flags/#edge-sleeping-tabs-immediate-timeout

      HotCakeX I don't know if you understood my concern. Tried doing that but obviously it won't change anything.. I need sleep tabs to immediately have affect on every opened tabs without any delay or time-out as it used to be before the update came.

        That happens on my systems already, Edge stable and Edge canary.

        please remember these two things:

        you can go here: edge://discards/

         

        and it shows you info about sleeping tabs features. there is a column called "can sleep?"

        and if a tab can't sleep, you will see reasons for it if you hover over the entries.

        common reasons are: 1)tab is added as an exception in Edge settings to never sleep. 2) tab is holding indexDB, 3)tab has notifications enabled

         

        there can be more reasons, Edge is smart enough not to break website functionalities that's why it watches website behavior because making decision whether to put it to sleep or not.

         

        to get immediate tab sleeping, you can turn on this flag:

        edge://flags/#edge-sleeping-tabs-immediate-timeout

         

        and then you will see here that it's set to immediately instead of custom timeout number

        edge://settings/system

         

         

        with these 2 pieces of info, if you still can't do this, then something is wrong on your side.

        you can begin troubleshooting steps such as reinstalling Edge, resetting Edge from settings, resetting flags, extensions etc.
