Steps to reproduce

  1. Open app
  2. See UTDs everywhere. No sync spinner.
  3. Wait minutes; they don't resolve.
  4. Later on, they do.

Outcome

What did you expect?

No UTDs

What happened instead?

UTDs galore, apparently caused by the e2ee sync loop taking 3 minutes to generate a response due to doing 30k devicelist calculations.
