That's weird. It's not a lot. When you rebroadcast and icons don't show up, can you go to your relay list, open your outbox relay and see if there is an error message down below?

I have a low follow count compared to what I think is normal. Under 200 follows. That is why the lower connections than normal I think.
I'll have to watch and get back to you on the errors. When I restart the app any notes with no relays disappear completely even for me. I ran a GrapheneOS update between posting these this morning and when you replied so they are all gone. No errors on my outbox relays right now.
Weird. Are you using the default privacy option? The default sends your posts to your relays outside of Tor, but if you changed, it might be a Tor issue.
I am using tor and it does cause some weirdness with notes posting. I'm pretty sure this isn't that. If tor isn't connected when I restart the note is still in amethyst for me to broadcast again, and broadcast works once I'm connected to relays again. Also I can see my relays are 0/XXX when tor is down. During this issue I see relays connected.
It looks like clearing app cache solved the issue so far. 2 days they post fine as a big single note.
