Toast "key storage out of sync" visible even though things seem fine.

[andybalaam]

Steps to reproduce

1. Log in
2. Successfully verify using another device

This was on a dev instance, so I uploaded the logs manually here:

console-export-2026-1-29_13-31-31.log.gz

Outcome

What did you expect?

To be properly verified, and to see no warning about it.

What happened instead?

I saw a "Your key storage is out of sync" toast.

But my crypto setup seems fine.

When I refresh, the toast does not reappear, which makes me confident that there is nothing actually wrong with my crypto setup.

I can reproduce on a local setup too

1. Create a new account on EW for new_guy
2. Start a direct chat with alice
3. There is a popup asking to setup recovery, just do it (follow the step, copy paste recovery)

From another context in a new tab:

1. Log in this new account
2. Verify with another device -> follow the step and verify succesfully.

Then you have this unexecpected Popup

I can see from the logs that all the secrets are received.

The failing check seems to be
