After I set alerts and change them to notification (I already set up mobile app) I close the terminal and once I open it back there're no alerts. I expected them to work even with a closed terminal and be able to get mobile notifications. Any chance to set them up like this?
Many thanks in advance!
Nope, alerts run from the terminal. If the terminal isn't running, no alerts.
You can look into getting a VPS if you want something "always on".
