We're investigating slow performance with home directories in the US region.
If you experience Nuke sessions where dialogs take a long time to close, try closing the session, going to https://dashboard.athera.io/account and 'Drop Cache' on 'Home'. This will cause the index of the home folder to be rebuilt.
Unfortunately we have an unrelated performance issue with indexing in the US. Its 20x slower than in the EU. This is being addressed by the engineering team.
You might have to wait some time for the indexing process to complete in the US region (20 minutes in my case) depending on the size of your home folder.
