TIFU: Subscription woes.

I was blessed with a benefit of Subscription for trying out Project Sigil. This benefit was due to end on May 10th. Today, to ensure no gap in service I tried to sign up for the year assuming the benefit would end on the 10th and my new Cycle would start. Previous to the Sigil Benefit I was monthly. 

I assumed I could end my monthly and buy the yearly and that would start at the 10th. I was unable to change. So I canceled thinking that would fix the problem. Now I have to reactivate on the 10th or 11th and do it on that date anyway and that makes me sad. Not world ending.  Not the worst deal ever. But worth noting this was a strange painpoint.
