Coracle and amethyst use different relay lists. Amethyst uses only the ones you listed. Coracle is dynamic, it adds and removes based on your follows. Check if the amount of follows is the same between both and see if resetting the relay list works.
It's very odd - everything else in Amethyst is working fine, notifications are no issues at all nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z - is this a glitch you e come across before? I'm on the play store version if that helps

I've not changed the relays I connect to on Amethyst but I'll give that a try once I've written them down
