Troubleshooting OAuth 2.0
Note:
Applications authorized using the OAuth 2.0 feature in your NetSuite production account aren't copied to your Release Preview account, sandbox accounts, or Next Preview account.

Each time a sandbox account is refreshed, users again must authorize applications explicitly in the sandbox account.
