Hello,
I turned on the notifications for my Trello app in my Iphone XR. Both the iPhone and the app are updated to the last version.
I don't get any notification even if all my trello items have the expiration date. I also tried to set a reminder 5 or 15 minutes before the expiration, but still no notifications at all.
Below you can see that the notifications are all turned on in both the app and the settings of my iPhone (the screenshots are in Italian)
