Why doesn't notifications.sendSimple send most of the messages?

Question

Classmates

In general, I can not understand whether this is normal or not. I send notifications to users via notifications.sendSimple, but about 70% of sends return an error. There are only two errors:
error_code":10,"error_msg":"PERMISSION_DENIED and error_code":25,"error_msg":"NOT_ACTIVE. So that's why error 10, for example, pops up when sent to people who EXACTLY go into the application. Every day they come, I track, and at the same time they did not authorize, how is this? iframe javascript application. The second error also often pops up for people who periodically log into the application. Maybe you need to use some additional token to send. For example access_token?

Try first to check if the user is actually a player in your application ( https://apiok.ru/dev/methods/rest/users/users.isAp...
And, if possible, send examples of such users (+ id of your applications) to [email protected]
