I thank you and nostr:npub14uc57wfq2zd0g3qh5lpvkq2svvkjl9fruzyxnz9zh95ev2japw7ql2g0sq for your ensuring efforts towards Nostrid app.
Please let me know how to save my choices of Relays (Settings -> Relays) in https://web.nostrid.app/, after I delete a few default Relays (uri), from the list of Relays, and add new ones. Every time I am seeing the default list again after making the changes.
