Delay in push notifications

Hi all,

For a couple of days, I have quite a delay in receiving push notifications from all my triggers. I confirms the problem but creating a new simple trigg with an Olisto Now test button sending a push notification when pressed.
I went through all the check points I could think of to try to fix the problem: notification settings are all on high priority, battery management is on “don’t optimize”, data usage is “unrestricted”, I cleared data and cache and rebooted the app. Nothing helped…
Do I forget something? I there any server issue at the moment?

Thanks in advance for your help!

Cheers, Nicolas
