Synching without opening App on iOS

[aimxoo0o]

Hello there! :)

I use the webinterfrace to create a task and set a reminder.

I won't get a notification on my iPhone, if I dont open the iOS App before.
I guess thats normal behaviour, but is there a workaround?

I dont want to open the app everytime I set a reminder. 

Is there no way to push a notification?

Thanks in advance! :)

Have You set the notification options in iOS?

Hey thanks for your reply!

Yes of course I have set the notification options in iOS.

I forgot to mention that I will get a notification If i open the App, let it sync and close it.
The problem is the background syncing.

The option "Background App Refresh" is enabled too.

Is there any update or workaround?
