You may be required to agree to a liability waiver before attending your first session. Depending on your version of the app, you'll have the chance to complete a liability waiver either when registering your account, or later from the Edit Profile screen.
When registering your account
Certain versions of the app require you to agree to a liability waiver at the same time that you create an account. If this is the case, the liability waiver will be shown directly from the Create Account screen.
If you choose to decline these terms, then your account will not be created.
From the Edit Profile screen
If you're an existing client of the business, or you were never asked to complete a waiver when signing up, then you can agree to the liability waiver from the Studio Liability Release section of the Edit Profile screen.
