New notes not syncing between iPhones

[rezzap]

Expected

I'd expect that when a new note is added, it would sync to all devices.

Observed

A user has reported that new notes only sync between iPhones after logging in and out. Works as expected when a note is created from the iPad, but when it's created from the iPhone it will not sync until it's logged in and out.

Reproduced

(user reported steps, I don't have 2 iPhones to test this)

1. Make sure you have Simplenote installed a two different iPhones.
2. Create a new note on one of the iPhones.
3. It does not appear on the second iPhone.
4. Log out of the second iPhone and back in.
5. The note appears. And any subsequent changes also appear, including deleting the note.
6. Create a new note.
7. It won't appear unless you log out and in again.

Same happens if the you reversed the roles, i.e. created on the second iPhone and had to log out/in on the first one to get the new note.

If you create a new note on the iPad, it just works as it should on both iPhones. The issue is specific to the iPhone.

Users has Simplenote on 2 iPhones and one iPad. All have the latest app 4.47.

The two iPhones are different versions, one iPhone SE runs 15.7.1, the other iPhone 11 runs 15.6.1. They suspect it's new to the latest iOS update as wasn't an issue before.
