I created new nostr account, posted notes on default relays, all ok .. I have my own relay and I want that account to only post on that relay so I removed all default relays and added my relay , now I started posting on that account, nostr clients where I never used this account previously showing only 1 relay and newly added notes while relays and clients where I previously posted still showing old notes and old relays list in profile.. why so ? is it cache issue ?
