Hello, this is a mass sent message.
You have been messaged because you made an annual subscription before.
I have received news with an issue, from Patreon support team.
If you have tried and are unable to register for a $10 plan, there will be a $15.01 plan available for limited time.
The rewards are the same. The price is old, and is the only way for people who used annual payment, there is no solution to get to cheaper plan if you paid for 12 months, only higher.
I am sorry, I hope things get solved with this.
