I notices too late about this issue :/ and I don't know if my answer will be useful as possibly the root problem is fixed somehow. However, I will reply in case this is needed for future use cases.
The To field is the same field used at the standasrd Webform email handler, as you mention it must be filled with either the manual list of emails or a token.
To add subscribers dynamically, it is needed to code it as it is not possible to dynamically get them out of the box. There are two possible solutions that needs to be evaluated:
- In a custom module, implement hook_token_info and hook_tokens to provide a token with the list of subscriber emails, separated by comma.
- If the subscribers are saved through a contributed module that manage newsletter subscriptions, a submodule into webform entity email can be created.
