We have a custom, one-off app that was built years ago using the merchant tokens generated in the Business Operations > API Tokens sections.
Based on @bryan.vargas's response in the post linked below, it sounds like these tokens will not expire after the update on August 1st requiring refresh tokens in the OAuth flow. Can anyone confirm if this is the case, or do we need to make updates for the merchant generated tokens from the Business Operations > API Tokens section?
