Google just emailed me too and I have to pay these manually or face service disruption. I have auto billing setup at so many places like porkbun, many Saas services, amazon, Google, digitalocean, etc.

God knows how many reminders I will have to add and how much time I will have to waste every month paying these bills by hand now and I hope I don't miss any.

I can only wish like digitalocean, amazon google too provide provisions to add account balance so I can add money as failsafe.
