Often, my relay setup gets reset and I have to redo everything. 🤷

Humm.. on the new version. This is a new bug, I will do some testing.
But make sure your 3 Public Outbox relays are receiving your posts.
I remember having this issue, too, over the last days. I'd make a change to my relays, scroll (maybe click) around the settings page, and find that my original change was lost. To work around it, I now make sure to hit Save after making a change and before moving on to another section of the relay settings.
