Hi Mark, are your existing access tokens OAuth 1 access tokens, or OAuth 2 access tokens?

OAuth 1 access tokens have two pieces, a key and a secret. OAuth 2 access tokens are just one long string.

API v2 only uses OAuth 2, so if you have OAuth 1 access tokens, you'll need to migrate to OAuth 2 first. You can do so using /oauth2/token_from_oauth1.

If you do have OAuth 2 access tokens already though, those should work between both API v1 and API v2 without issue. In that case, please share a sample request/response of the issue. Just be sure to obscure some of the access token for safety.
