Server taking too long to respond when updating display name and shown error despite success

### Steps to reproduce

### Outcome

#### What did you expect?

#### What happened instead?
App is blocked by a spinner, which after a few minutes changes to a "server taking too long, try again later" error dialog

Even though the error tells me that the display name update failed, it's actually succeeded
