I understand that with dev credentials we cannot refresh token for any other accounts except the dev account, but with a production credentials (and shareable url), I believe this should be possible.
A test user is able to access and install the app and get a token and refresh token.
However, I get an error “error”=>“invalid_grant”, when trying to refresh the token.
Also, I believe I had requested a shareable url around 20 days ago, but already got a notification that it has been 30 days and it will expire. A little confused by that.
