I just saw this again as Amandine logged into EXI on macOS for the first time - having verified her device, most of the room previews were blank until something happened in the room, which felt like a really flakey FTUE
I think https://github.com/matrix-org/matrix-rust-sdk/pull/3018 should help with this.
this is entirely reproducible btw, so should be easy to check :)
We first need to create an integration test to verify this (complexity: S). Then, we may need to fix the problem itself.
We do have an integration test for this, so it should really be fine — if it's not please reopen.
