Hello @ChildrensFriend. I'm sorry that you are having trouble navigating your account. May we ask what exactly you were having difficulty finding? We'd like to help you with this and send over any feedback that you might have over to the appropriate team.
Also, your templates have not gone anywhere! You still have access to your saved templates and also the many premade, customizable templates that we offer in your account. All you have to do is go to Create under the Campaigns tab and click on Email. This will bring up your saved templates and the templates that we offer. Please let us know if you have any more questions.
