localNotificationSchedule isn't showing the notifications on the appropriate user timezone on iOS 14.

[enrickdl]

Hey everyone,

I'm facing this issue where I'm not able to receive local notifications on iOS devices that are running iOS 14. Android devices are working fine, iOS devices <= 13 is working fine, but only the iOS 14 isn't.

I've tried a few solutions but none seems to solve this issue.

Any clues about that?

Let me share my settings:

Just an update, as seems to be related to #188, I did receive the notifications after all, but 3 hours later (since I'm on UTC -3). So appears that iOS 14 is not converting the date for the user timezone.

I created a PR to solve this, #354. Feel free to take a look, and leave feedback.
