You might be logged in with public key only. Please check that you logged in with a private key! Many people have been confused by this, so I'll add a notification.

Unfortunately no. I checked again. I always log in with private key.
*logged in with a private key or browser extension like getalby.com
I have no idea why, but it works now 😂
I saved pub key as username on iCloud Keychain. Auto-fill expects a second field to appear for password. Why is even possible to "log-in" with just the pub key? Another issue now I can see my private messages but not the answer to them.
Pubkey login can be used for viewing nostr from someone else's perspective, or viewing your feed or notifications even from a device where you don't have the private key. Good to know about the auto-fill!
