@Panther7: That's strange. The Galaxy Store link should be visible at the bottom of the screen, below the existing Edge panel options via Settings > Display > Edge Screen > Edge Panels. Have you registered a Samsung account to your Z Fold 2 and Tab S7, and can you access the Galaxy Store as standard by tapping on the app thumbnail? Are you able to share a screen shot of the Edge Panel menu to give me an idea of what you're seeing?
@Panther7: It may be the case that some of your Galaxy Store options are restricted because the devices were intended for use outside your current region. With this in mind, where did you purchase your Tab S7 and Z Fold 2 from, and where are you currently based?
