However, Patchwork didn't pick up the v2 cover letter at all, so I thought replying to v2 would mess up the thread even more. That being said, the v3 cover letter is not visible there either. Should I resend this as v4 [which message to reply to?] or send a completely new series perhaps? I apologize for the confusion, this is my first time doing that.
