Steps to reproduce

The migration appears and stays for about 30 seconds, the usual suspect time

Outcome

What did you expect?

Even if a SS proxy the room list should appear instantly

What happened instead?

I had to look at this migration for a long time.

Should we kill this screen with Simplified Sliding Sync?

https://github.com/matrix-org/matrix-rust-sdk/pull/3822 may improve the loading state.

It is fine to entirely remove this screen. It is no more required with SSS (https://github.com/element-hq/element-meta/issues/2497). We do not need to make onboarding with the SS proxy as smooth as possible. It will be deprecated soon.

The migration screen has been removed in #3389.

But now user may see a "loading" room list for a long time if the server takes time to answer the request.

During my test with account creation using OIDC, it was instant though.

I guess we can close the issue?

I let you decide @manuroe .

Yes, we can close this issue. We target SSS now. The initial sync is instant. No more need for a SS proxy to do a slow v2 initial /sync Thanks @bmarty !
