Homey won't send me push notifications

Hello, I have for a few days problem with sending notifications. Homey just won’t do it. I made very simple flow and test it and here is result…just red warning triangle. Any suggestions?

If you test it what is the error on the red bar on top of screen?


That’s new to me. Sometimes it is “rate_limited” when too many msgs in a certain timeframe were sent.
Did you reboot Homey? Turned off power for 15mins?
Can you send push msgs to an other Homey user?
