Long Access token deprecation time

Long-lived access tokens are now considered deprecated, but we don't currently have a plan to disable existing long-lived access tokens. (If that changes, we will of course announce that ahead of time.) That being the case, you can continue using existing long-lived access token(s). Note though that after the change you won't be able to create new long-lived access tokens.

You can find more information on this migration in this blog post. That change, where Dropbox will no longer return new long-lived access tokens, is planned for September 30th, 2021.
