Did you share the notification? Then it's expected.
that is to say that if the admin creates and assigns them, everyone can modify them? In that case, if I am correct, each user must create them and they will be kept on their devices only?
yes, confirmed that way, thank you very much for pointing it out
As an admin you can create notifications for other users, but if you want each user to have their own instance, you have to create a separate instance.
Greetings, I just noticed that if a user presses the ALL DEVICES box in notifications, it modifies all of the other users, even if he is not admin, is there any configuration or setting so that this does not happen?
