DSDApp is still available for you. You still can use the DSDApp to complete or modify your designs. However, once the DSDApp is phased out (in 12 months) you will not be able to go back and modify them. To prevent yourself from being in this situation, we encourage you to upgrade to the new solution, and import all of the patient documentation for the patients with year-long treatments into the SmileFy app so that you can design the case, and have no worries about future modifications.
