Thank you for your answer. Yes, i found out it. That‘s I use tight now, just wanted to know, maybe we have a way to short amount of created notifications.

Hey, thank you. Answering on your question - yes I tried, but we're talking about little different functionality! Code above can help me make repeat every day when time equal 8 hour and 30 minutes! I'm looking for way to repeat notification every hour, starting from specific time.
