Due to Vimeo's privacy restrictions, any Vimeo videos added to the exercise library won't play for your clients unless our domain is added to your Vimeo 'whitelist'.
To do this go to your Vimeo account, under the Privacy Tab to add TrueCoach as an acceptable location for your videos to be embedded.
For additional info see this link for Vimeo's Help Center Article on privacy settings.
And voila! If you have any issues, please reach out to us!
