Why is my calendar notification disappearing after a while?

[Android Central Question]

So i bought a new phone (galaxy s9+)
And i realized that after an hour and a half or so the notification of the reminders i have disappearing and act like i swiped it.
I changed the remidera to have no 'end time' but that doesnt work as well.
I literally live by my remiders and have to solve this problem asap.
Any help please?

I did some testing and it appears that Samsung Calendar and Google Calendar pull down the notification after the end time has passed.

I use aCalendar+ and this persists the reminder until i send it away. Link -> https://play.google.com/store/apps/details?id=org.withouthat.acalendar

I cancelled the 'end time' of the calendar but the reminders keep on disappearing...

I really like aCalendar. It shows the dates and events in formats that I find more intuitive.
