My Question or Issue

The Spotify OAuth app is in dev mode. Did not sign up for extended quota mode.

It's been more than 12 hours and the refresh token is still returning 429 Too many requests on v1/albums and /artists

How do i revalidate auth without waiting longer?

Check whether your app has been disabled/blocked. I was experiencing this issue and only discovered this days later.

sorry, where did you determine that? I searched for it in email and in settings page but did not find any indication that it is blocked. 
did find a a few app block & appeal threads

You can find it at your developer dashboard.

Remember to implementere back-off behavior. The 429 response will tell you how long you must wait in seconds. Initially it’s not long, but it increases for each additional request.

My experience is that as soon as it triggers, it increases to infinity.

I deleted the cookie that held the refresh token. now it is working with the new access token without any blocker
Also, I now use the batch V1 endpoints to get several items and minimize requests

What does the response say? It SHOULD have a retry-after header with a value in seconds. I doubt it’s literally infinity, but is it a really high value? Are you sure you are dealing with the response properly, because if you call 10 times per second, it’ll grow FAST since each request adds time exponentially IIRC. So after a 100-200 requests, it could be high. 

if your first 429 response has a really high value, that would be a bug IMO, and you should report it.
