SubscribeStar is notoriously slow to respond to new creators. Some have waited over a year. They are criminally understaffed, so some applications are just collecting cobwebs.
Oh, that's what happened to me. I've just sent my petition, they just told me that they coudn't pay to my country (I replied them back that through their partner, Fiverr, they could pay me) and never heard of them again. Sigh, I know they are understaffed but they could at least put some effort on the new creators on their platform.
