ritardo sui crediti generativi

Good morning, I'm writing here because my Firefly payment automatically renews on February 6, 2026, and even today, February 8, 2026, the program still tells me I don't have credits to generate content. The account screen says the next recurrence is February 13th. So why pay on February 6th to only be able to generate from the 13th to the 6th of the following month, thus only having about 23 days to use the credits? Thank you.
