Do Not Disturb Schedules are deleted when Game Mode has been activated

[Mahnas92]

DND Schedules work as intended, until I play a game that activates Game Launcher/Boost and DND Game mode is activated.
There is even 100% reproducability on this:

Procedure:
1) Go to DND settings, create new Schedule.
2) Open any game that triggers Game Launcher/Game Booost/Game mode (whatever name it has), so that a Game Mode DND profile is activated.
3) Close game and go to DND settings again.

Expected Result:
- My schedule is still there.

Actual Result:
- My schedule seems to be gone.

I've had this issue for a while, but I don't play games that often, so didn't figure it out until recently, when it happened more frequently, and today I suspected it is the game mode when I realized there is a DND Schedule imposed by Game Mode.

I have this problem too, maybe it is just what happens when you do this.

[Mahnas92]

Yeah, but I can't take "this is just what happens" for an obvious bug like this on a flagship device that is supposed to have basic smart phone functionality like DND schedules and seamless gaming experience.

Yes, this is a huge problem! Fix it!

THIS IS THE FIX -- SAMSUNG you can ask my bank details later or just fix it yourselves

Problem is with game booster. 

Until the last update I would roll back game booster update and not update it which resolved the issue.... now I can't downgrade. 

SO TO FIX IT DO THIS:-

under settings - apps - samsung app settings - game booster - about game booster "i" info icon top right - appear on top .........  "turn it off and then turn it back on". Fixed mine -- no more deleted Do Not Disturb

One more with this problem. The fix didn't work for me. Disabled it for now.
