Why doesn't qq upload an album to remind friends to read and write about reminding friends?

1. No photo album is set to be visible to the outside world. Only when the photo album is set to be visible to the outside world will a reminder be sent to friends.

2. A friend may have set that he doesn't need to receive photo album dynamic reminders. In this case, only some friends can be reminded to see it.

3.QQ friends may have set up blocking dynamic reminders. In this case, only other friends can pay attention to the album.
