Have you provided an initial effort estimate for this issue?

I have provided an initial effort estimate

The browser's history is impacted by the oAuth authentication procedure between the instance and the FlowFuse platform in which two redirects occur (one in /account/authorize and the second in /account/complete/:code).

For the time being, I have no practical solution on how to solve this, or if it should be solved as it's a core component in the auth process.

@knolleary, I assigned you as well so we won't loose track of it

not something we can easily fix, moving it to todo as other priorities take precedence

We've been carrying over this over multiple release versions and has no urgency or immediate fix that can be addressed as the oauth redirect is integral to the NR authentication process.

We should remove it from the current release and re-schedule it when needed.
