Plz check the message settings (Pixiv Fanbox)

I am sending you download links and passwords to Pixiv's messaging system when they are updated, and when you start a new subscription.

But if you set the message's settings to "Only Pixiv verified accounts", I can't send you a message!

That's because that option is to receive messages only from Pixiv's management.

If you want to receive the download link and password, please select "All accounts" or I can't provide you with the download link and password.
