can i use magic media for my digital products ? will customers still have an opportunity to change it to something else after purchase if they have the free canva?

Am I able to get feedback on my mockups for my first product I’ve created?

Good morning ,I have been creating a couple of journals to start of my first shop but now I’m seeing videos that I shouldn’t use canva pro items to design because people who don’t have pro won’t be able to redesign after purchasing..is this true? Now I feel lost and back to zero

Good afternoon I’m a woman of multiple trades and want to jump on this digital marketing journey and I’m looking for help on how and where to start and be successful in it
