Unity’s provider agreement does not guarantee payment on the 15th, and due to other factors such as a bank holiday, Unity gave advance notice that this month’s publisher payout will be delayed. If you’re a publisher, keep an eye on the Asset Store Publishers forum section so you can stay up to date on information like this. (Instructions to access the Publishers forum section is in your assets’ acceptance email.)
Thank you for the information,
I rarely enter the Forum here, but since I sent the question to support and saw that the link generated by them gave an error 404, I thought it could be another more serious failure.
Because soon I will send new assets to the Unity store.
