Payment/Billing Bug Post Update

After the update I'm incapable of altering my payment info; I haven't used Inkarnate in months and haven't needed to, but the payments continue to be taken from my account. Wouldn't be an issue if I could just remove the billing info, but that's inaccessible, so I'm forced to pay. This needs to be addressed urgently; As Inkarnate is effectively holding my info hostage and taking money from me without my consent.
