Problem

Users are experiencing messages in the browsers console as a request fails due to an expired access token.
Even though these errors doesn't inflict any functional pain on developers or their users, we they're a slight inconvenience and we should eventually find a way to get rid of them.

Solution

Two solutions comes to mind:

1. Check the expiration of the access token and compare it to the browsers time and ensure to preflight a request to refresh it if it's expired.
2. Refresh the access token on a timeout, to ensure it is refreshed ahead of time, before a request is made.

I would suggest we go for option 1, since 2 is not guaranteed to actually refresh before a request (ex. the computer was hibernating as the timeout should fire). Also option 2 would probably cause warnings in React Native (as scheduling a timeout in the far future does).

How important is this improvement for you?

Fairly niche, but nice to have anyway.
