Hello Everyone

Lastnight i successfully set up my app using the Getting Started Guide. I was able to setup Postman and connect.  I used to OAuth and got the code and was able to view all my activities on Postman and on this Strava API tutorial.  https://youtu.be/sgscChKfGyg

Today however nothing works. Im sure its bc my access token is expired but I cannot figure out how to refresh it.  Ive tried the tokens from my Strava API page and the new tokens i got from the OAuth yesterday on Postman to no avail.  I can re-run the OAuth url and get a new code but and it returns new tokens but they dont work.

I appreciate any help.
