This one is tricky! Based on the conditions and behavior, it sounds like a relay interaction issue. I tested the workflow just now between Primal and Ditto, which seemed to post successfully.
Are you using the default relay (Primal)? If you close and restart the PWA/Browser, does it still fail? Does it work on a different device, also?
Thank you for reporting this in any case, we'll find a solution yet. 🙂 https://video.nostr.build/e9c10c9d4415c9205b5de52da9465a054524cd914fc0d0212f9b3d1f61492869.mp4
