Hello @Toni_Krstic!
When you deactivate the Legacy toogle it will ask you to reconnect the account, do it, associate your site and return to the scene and the sites will work for you.
At least this works for me.
I would also like to tell you that capturing form submissions does not work, since the node has an error when requesting the webflow scopes necessary to work.
@ria Yes, I have all the permissions, but looking at the node code I have seen that the scopes are incorrectly requested, since they are only being sent:
cms:read cms:write sites:read
When should they be sent:
cms:read cms:write sites:read forms:read
I have sent a PR to solve this and it is waiting to be reviewed Update scopes in WebflowOAuth2Api.credentials.ts for form submissions by oscarpedrero · Pull Request #10554 · n8n-io/n8n · GitHub
