#### Logs taken while reproducing problem

Start by reproducing the AF Embed configuration on AEM 6.5 SP17 with AEM Forms 1.1.27-wcmB004, then trace how the embed and embedded Form submit-action settings are applied. Done means the Thank You Page configured on the AF Embed component controls the redirect instead of the page authored in the Form.
