So far my experience with nostr:npub1yzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesnxrf8q is terrible. Twice I lost a bunch of writing in the last session I used it. When I saved a draft all of the relay's timed out, after saving it takes you to your articles page so it's not like you can retry to save the draft. Although, you can in the little notification you get, but that didn't work for me.
Discussion
1 - you are one of the few who reported such things
2 - its impossible all relays timedout except if your connection is not okay
3 - when timedout you can click on the details to retry which is the fastest way
4 - your feedback is welcomed, thanks.
