Hi,

I noticed that it indeed didn't work. 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.

Regards
Kuba
