We fixed a bug regarding this in the latest release. It was a subtle race condition when zapping too fast. Hopefully we'll find all edge cases eventually until there's nothing more we can do to increase reliability except tell you what you have to do.

How is your non-custodial setup doing?

I simply switched from 1 custodian to another. Since SN don't want to hold my sats anymore, I switched over to Coinos to hold my sats. Overall personal experience had been mostly the same as back when SN was custodial, except for the occasional "zap on comment fail". But even those tend to work if I try again later.
